But you need to determine whether you need a higher power power adapter according to your own accessory usage,12V/5A is recommended) -
Windows/Ubuntu System
¶ BPI-R4Pro bootstrap setting
The tables below list the settings of the switch (SW3) and their functions.
-
All Jumper is "1", BPI-R4Pro will boot from SD card
-
SW3-A is "0" and SW3-B is "1" , BPI-R4Pro will boot from SPI NAND
-
SW3-A is "1" and SW3-B is "0" , BPI-R4Pro will boot from eMMC
-
If the console said "system halt!", it means that the bootup storage does not cotain any OS
System halt!
¶ Flashing image
If you want to change the factory default system to another one,
Place Download the image file into a windows/ubuntu PC and follow the steps below.
¶ How to flash image to SD card
|
Please low level format the SD and clear all data of SD. It’s very important. Otherwise, you will encounter a "jffs2" error during the startup process. |
-
Please follow the following diagram for Windows PC.
-
Linux PC, you can use the "mksf" command for formatting, or use the "dd" command to write zeros.

Install bpi-tools on your Ubuntu. If you can’t access this URL or any other problems, please go to bpi-tools repo and install this tools manually.
apt-get install pv curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash -
After you download the image, insert your TF card into your Ubuntu. Execute
bpi-copy xxx.img /dev/sdxto install image on your MicroSD card
-
After step 3, then you can insert your MicroSD card into R4Pro,Change Bootstrap to boot from SD, and power power R4Pro.
¶ How to flash image to NAND Flash
Before flashing image into Nand, please prepare a USB disk. Let’s take OpenWrt image (mtk-bpi-r4pro-NAND-20250928.img) for example, the steps are below:
-
Format the USB disk to FAT32.
-
Copy Nand boot OpenWrt image(mtk-bpi-r4pro-NAND-20250928.img) to USB disk.
-
Change the bootstrap to sd boot, then power up the board.
-
Plug in USB disk to the board, and mount the USB to /mnt or other directory as follows: (you can skip mounting if it is mounted automatically)
mount -t vfat /dev/sda1 /mnt cd /mnt -
Execute following command to erase the whole Nand flash and copy image to nand device:
mtd erase /dev/mtd0 mtd write mtk-bpi-r4pro-NAND-20250928.img /dev/mtd0 -
Power off BPI-R4Po, remove u-disk driver, change bootstrap to nand boot and power up again.
¶ How to flash image to eMMC
| Because SD card and EMMC device share one SOC’s controller, it is necessary to switch to NAND startup and then burn the EMMC image into the EMMC. Finally, you will change the boot to boot from EMMC. |
Let’s take OpenWrt image (bl2_emmc-r4pro.img, mtk-bpi-r4pro-EMMC-20250928.img) for example, the steps are below:
-
Format the USB disk to FAT32.
-
Copy EMMC boot OpenWrt image(bl2_emmc-r4pro.img, mtk-bpi-r4pro-EMMC-20250928.img) to USB disk,
if the image is compressed please uncompress it before copying to USB disk. -
Change the bootstrap to Nand boot and poewer up R4Pro.
-
Plug in USB disk to the board, and mount the USB to /mnt or other directory as follows: (you can skip mounting if it is mounted automatically)
mount -t vfat /dev/sda1 /mnt cd /mnt -
Execute :
echo 0 > /sys/block/mmcblk0boot0/force_ro dd if=bl2_emmc-r4pro.img of=/dev/mmcblk0boot0 dd if=mtk-bpi-r4pro-EMMC-20250928.img of=/dev/mmcblk0 mmc bootpart enable 1 1 /dev/mmcblk0 -
Power off BPI-R4Pro, remove u-disk driver, change bootstrap to emmc boot and power up again.
¶ Power ON
-
Using your USB TypeC cable Connect to debug console(CN41) on BPI-R4Pro
-
Install Terminal Emulator or use a serial terminal that you are familiar with，
change the setting as follows: Baud=115200,Data bits: 8bit,Parity: none,Stop: 1bit, Flow control: none; -
Set up the bootstrap before supplying power，
（If you are using BPI-R4Pro for the first time, it is recommended to set it to NAND boot) -
when Connect power adapter to DC-IN connector(CN44),Green LED “PWR” light up，
And there will be characters similar to the following on the console.
This means you have successfully started BPI-R4Pro.

¶ 10G Ethernet
MT7988A has two USXGMIIs for 10G ethernet, of which USXGMII Port1 is used as a WAN port (10G SFP+ WAN/10G RJ45 WAN), USXGMII Port0 is connected to USXGMII0 of Switch MxL86252C, and USXGMII1 of MxL86252C is used as a LAN port (10G SFP+ LAN/10G RJ45 LAN)
The SFP serdes speed of BPI-R4Pro is fixed at 10Gbps, so only SFP that support this can be used！
Tested 10G SFP+ Copper/Fibre Module
¶ 10G WAN
¶ Block Diagram
¶ 10G SFP+ WAN
When MT7988A’s GPIO3 ouput=High, USXGMII Port1 switches to SFP+ WAN Port.
At this time, 10G SFP+ WAN is functional, but 10G RJ45 WAN will be ineffective.
Now, you can insert a 10G SFP+ Copper/Fibre Module to get a 10G network interface.
Or you can also insert a 10G XGSPON Stick to access the Telecom operator’s network.
|
Our default image configuration: After inserting the SFP module, USXGMII will automatically switch to 10G SFP+, and 10G RJ45 will not be usable； Therefore, if you want to use 10G RJ45, do NOT insert the module on SFP+. |

root@R4Lite-C:/#¶ miniPCIe Slot(For WiFi NIC)
You can insert the BPI WiFi NIC into CN7 and CN9 on top of BPI-R4Pro, and then fix it with two M2 screws.
¶ 12V Power ON/OFF
BPI WiFi NIC module requires 12V power supply, so the power supply on the BPI-R4Pro must be turned on before powering on.
(SW4 is turned to the "ON" position, and the 12V LED will lights up when power on)
|
The 12V power supply will be supplied to the BPI WiFi NIC through PIN6/28/48 of the miniPCI socket. When plugging in other modules, be sure to turn off SW4 if you cannot confirm whether the module can withstand 12V. |
¶ 3.3V Power adjustment
Three GPIOs extended from PCA9555 can be used to turn off and the voltage of PCIe 3.3V adjustment.
Normally you do not need to adjust this voltage.
Details
| miniPCIe Slot 3.3V Power | ||
|---|---|---|
GPIO |
Output=High |
Output=Low |
PCA_A_IO1_0/mPCIe_A_PDN |
PCIeA_3P3V = ON |

PCIeB_3P3V = ON |
PCIeB_3P3V = OFF |
PCA_A_IO0_7/mPCIe_AB_Vset |
PCIeA_3P3V=PCIeB_3P3V=3.57V |
PCIeA_3P3V=PCIeB_3P3V=3.3V |
¶ PCIe
The BPI WiFi NIC BE14/BE19 requires two 2lane PCIe , but the standard for miniPCIe slots only defines one 1lane PCIe.
Therefore, we used two miniPCIe slots and modified the pins 17/19/45/47 of each slot to be the second lane signal of PCIe.
Except these four PINs, the others are standard definitions, so you can also use other modules.
¶ USB2.0
The two miniPCIe sockets each reserve a pair of USB2.0 signals extended from the USB2.0 HUB for expansion of other modules.
¶ M.2 B-KEY Slot(For 4G/5G Cellular Module)
The BPI-R4Pro has three M.2 B-KEY slots, all for 4G/5G Cellular Modules.
Each slot supports a pair of USB2.0 and USB3.0 signals, both extended via a USB 3.0 hub.
In addition, the CN15 and CN18 slots each have an additional PCIe3.0 1lane signal.
¶ Power
All modules are powered by independent DC-DC step-down.
GPIO can be used to shut down the power output and adjust the output voltage.
¶ Power ON/OFF
The power on/off control is as follows.
Details
| M.2 B-KEY Slot Power | ||
|---|---|---|
GPIO |
Output=High |
Output=Low |
PCA_A_IO0_0/BKEY-A-PDN |
VDD_BKEY_A = ON |

VDD_BKEY_B = OFF |
PCA_A_IO0_4/BKEY-C-PDN |
VDD_BKEY_C = ON |
VDD_BKEY_C = OFF |
¶ 3.3V Power adjustment
The operating voltage of most 5G modules is 3.3V~4.2V. Due to the large current, using 3.3V will cause module instability,
so it is recommended to adjust it to 3.95V.
But before adjustment, please make sure that your 5G module can withstand 3.95V!!!
Details
| M.2 B-KEY Slot 3.3V Power adjustment | ||

VDD_BKEY_B = 3.3V |
PCA_A_IO0_5/BKEY-C-Vset |
VDD_BKEY_C = 3.95V |
VDD_BKEY_C = 3.3V |

¶ SIM Card
Each M.2 B-KEY Slot supports two sets of SIM card signals.
We connected SIM1 to the onboard NANO SIM Slot and SIM2 to the eSIM.
However, the eSIM does not have components. If you need it, please contact our sales.
¶ Onboard NANO SIM Slot
SIM1 can use the onboard NANO SIM Slot or an external SIM Slot (this requires a self-designed expansion board connected via CN45)
when "PCA_A_IO0_6/SIM_SEL" Output=Low,SIM1 Connect to Onboard NANO SIM Slot,
when "PCA_A_IO0_6/SIM_SEL" Output=High,SIM1 Route to FPC Connector,
¶ External SIM Slot Conector
The SIM card signals from the three B-KEYs and two miniPCIe sockets can be connected to the FPC Connector (CN45).
This allows you to easily design a SIM card adapter board to fit your enclosure.
¶ eSIM
PIN42/44/46/48 of M.2 B-KEY Slot is the second set of SIM card signals.
Of course, this requires your module to support it.
¶ Cellular network LED
PIN10 of each M.2 B-KEY Slot is connected to an LED. This LED is the module’s network status indicator output.
For specific functions, please refer to your module’s datasheet.
¶ External LED Conector
We also route the LED signal to FPC slot(CN40).
If necessary, you can design an LED adapter board to adapt to your enclosure.
¶ USB3.0
Most 4G/5G modules can use USB2.0/USB3.0 for communication.
¶ PCIe
MT7988A has only four PCIe, two of which are used for WiFi connections,
and the other two PCIe3.0 1L0 and PCIe3.0 1L1 can be routed to M.2 M-KEY or M.2 B-KEY.

PCIE_1L_1 = M.2 M-KEY(CN14) |
PCIE_1L_1 = M.2 B-KEY(CN18) |
¶ M.2 M-KEY Slot(For PCIe NVME SSD)
The size of the M.2 M-KEY Slot is 2280, which can be connected to PCIe NVME SSD or PCIe to SATA, PCIe to Ethernet and other modules.
However, because the PCIe signal is multiplexed with the M.2 B-KEY Slot,
if you want to use it in the M.2 M-KEY Slot, you need to set GPIO79 or GPIO63 output high,
so that the corresponding signal can be switched over.

However, the MT7988A only has one controller of MSDC, which outputs two pinmux ports for SD 4.5 and eMMC 5.1,
so you can only choose between SD and eMMC functions.
¶ FAN
The BPI-R4Pro has two fan connectors, with pin assignments compatible with 4-wire PWM-controlled fans on Intel PC motherboards.
It operates with a 12V supply voltage and supports PWM speed control, but lacks a sense pin for speed detection.
These two FAN connectors are controlled by the same PWM (GPIO57_PWMD0).
¶ RTC
Built-in one RTC clock chip, and you only need to install a 3V CR1220 battery to work.
¶ EEPROM
Built-in one EEPROM chip (P24C02A), can be used to store small amounts of data.
¶ Buttons
¶ LEDs
BPI-R4Pro has LEDs to indicate various operating states, including power, WiFi, Ethernet, 4G/5G cellular, SSD, etc.
-
1x Power Green LED, Silkscreen "PWR" on the PCB，lights up when powered on and cannot be controlled by the software.
-
1x Status Red LED，Silkscreen "R" on the PCB，Controlled by GPIO "PCA_A_IO1_7/SYS_LEDR".
-
1x Status Blue LED，Silkscreen "B" on the PCB，Controlled by GPIO "PCA_A_IO1_6/SYS_LEDB".
-
3x WiFi Status Blue LEDs,The silk screen printing"W2G","W5G","W6G".
The specific function depends on the module. Some modules do not have this function (including BPI-BE14 V1.0). -
2x SSD Status Blue LEDs,The silk screen printing"SSD1","SSD2", Controlled by SSD.
-
3x 5G cellular Status Blue LEDs,The silk screen printing"SIM1","SIM2","SIM3",Controlled by 5G Module.
-
Each 10G/2.5G RJ45 has two LEDs, and each 1G RJ45 has one LED to indicate the network status.
¶ DC-IN
BPI-R4Pro requires a single +12V supply,and has multiple power supply , including DC power adapter, USB PD, POE, etc.
The supply voltage range is 9~24V, 12V or 20V is recommended, and it will automatically shut down when it exceeds 25.3V.
¶ DCIN(5521)
You can use a 12V/5A power adapter and plug it into the CN44 to power it.
However, if other power supply exist at the same time, it will be switched to other power supply.
The dimensions of the CN44 slot are as follows(Inner Positive, Outer Negative):
¶ DCIN(VH396)
You can also use a VH3.96 plug and connect it to CN6 for power supply.
The dimensions of the CN46 slot are as follows:
¶ USB TypeC PD
The USB Type-C PD connector is connected to a CH224K chip, which is used to communicate with the USB adapter and allow the adapter to output 20V voltage.
It is recommended to use a PD power supply that can output 20V and 65W or more.
¶ POE
You can use the BPI-RT5400-12V module, but this module does not exceed 30W at most. So when more peripherals are connected, the power consumption will exceed the maximum power of RT5400. Therefore, it is recommended to change to other power supply.
¶ DC-OUT
BPI-R4Pro has two power output sockets, but it is not recommended to use them to connect too many devices,
because it consumes too much power and may cause BPI-R4Pro to work unstably.
The dimensions of the CN2/CN3 slot are as follows:
¶ DCOUT(CN3，XH2.54-2PIN)
Connect directly to VDD_SYS_IN, the output voltage is equal to the input‘s.
¶ DCOUT(CN2，XH2.54-4PIN)
This slot provides two voltage outputs: +12V and +5V. The +5V is generated by the MT6682A PMIC. This voltage supplies power to many other devices, so it’s recommended not to connect high-power devices to avoid affecting system stability.
The 12V is generated by a separate DC-DC converter, capable of providing approximately 3A.
¶ 26PIN GPIO Header
The 26-pin GPIO Header contains 17 GPIOs. All GPIOs are 3.3V. Some GPIOs can be set to JTAG, I2C, UART, SPI and other functions.
