Introduction
Banana Pi BPI-R3 Mini Router board with MediaTek MT7986(Filogic 830) quad core ARM A53 chip design ,2G DDR RAM ,8G eMMC flash onboard,It is a very high performance open source router development board,support Wi-Fi6 2.4G wifi use MT7975N and 5G wifi use MT7975P, support 2 2.5GbE network port.
MediaTek MT7986(Filogic 830)
The MT7986(Filogic 830) integrates four Arm Cortex-A53 cores up to 2GHz with up to 18,000 DMIPs of processing power and 6Gbps of dual 4x4 Wi-Fi6 connectivity. It has two 2.5g Ethernet interfaces and serial peripheral interfaces (SPI). Filogic 830‘s built-in hardware acceleration engine enables fast and reliable Wi-Fi offloading and wireless network connection. In addition, the chip supports Mediatek FastPath™ technology, which is suitable for games, AR/VR and other low-latency applications.
Wi-fi 6 has many advantages over its predecessors, including lower latency, larger bandwidth capacity and faster transmission rates. Wireless network devices supporting the 6GHz band mainly use 160MHz wide channel and 6GHz uncongested bandwidth to provide multigigabit transmission and low-latency wi-fi connection, providing reliable wireless network for streaming media, games, AR/VR and other applications.

How to burn image to SD card
A. Note: burn image to SD card on linux computer 1.You could download latest image from our forum * Here is the example image link: 2.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 3.After you download the image, insert your TF card into your Ubuntu * Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card 4.After step 3, then you can insert your TF card into R3, and press power button to setup R3 B. Note: burn image to SD card on windows computer 1. Download the tools from the website: https://sourceforge.net/projects/win32diskimager/ 2. Install the tools into Windows computer. 3. flash image into SD card. C. Change Boot Jumper to boot from SD, Enable SD Card Device.
How to burn image to onboard eMMC
Note: because SD card and EMMC device share one SOC's interface, you need flash one SD image firstly, then R3 boot from SD card, then flash nand image into Nand, then change boot strap to boot from nand, you need flash EMMC image into EMMC. Finally you change bootstrap to boot from EMMC.
Before burning image to eMMC, please prepare a SD card with flashed bootable image and a USB disk. Let's take OpenWrt image (mtk-bpi-r3-SD-WAN1-SFP1-20220619-single-image.img, mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin, bl2_emmc.img, mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img) for example, the steps are below:
1. Insert the flashed SD card and power on to start the board.(the image "mtk-bpi-r3-SD-WAN1-SFP1-20220619-single-image.img" on the SD card can be OpenWrt or other linux OS like ubuntu...)
2. Copy Nand bootable and EMMC boot OpenWrt image(mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin, bl2_emmc.img, mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img) to USB disk, if the image is compressed please uncompress it before copying to USB disk.
3. 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
* change your directory to the mounting point, here is : cd /mnt
4. Execute following command to enable and copy image to nand flash:
* mtd erase /dev/mtd0
* dd if=mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin of=/dev/mtdblock0
5. Shutdown, remove SD card, and change bootstrap to boot from nand flash and change SD/EMMC switch jumper to EMMC, restart the board from Nand Flash.
Note: Enable EMMC device, boot strap is from nand
6. repeat step 3, mount u-disk to /mnt, Execute following command to enable and copy image to EMMC device:
* mount -t vfat /dev/sda1 /mnt
* echo 0 > /sys/block/mmcblk0boot0/force_ro
* dd if=bl2_emmc.img of=/dev/mmcblk0boot0
* dd if=mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img of=/dev/mmcblk0
* mmc bootpart enable 1 1 /dev/mmcblk0
7. power off R3 board, remove u-disk driver, change bootstrap to boot from emmc device.
Note: Enable EMMC device, boot strap is from EMMC.

GPIO
26 Pins Definition
GPIO Control
- echo xxx > /sys/class/gpio/export
- echo in/out > /sys/class/gpio/gpioxxx/direction
- echo 0/1 > /sys/class/gpio/gpioxxx/value
Check the base gpio, you could see mine is 411
For example: if you want to change gpio 22 as out highlevel, you need input commands like this：
- echo 433（22+411） > /sys/class/gpio/export
- echo out > /sys/class/gpio/gpio433/direction
- echo 1 > /sys/class/gpio/gpio433/value
FAN
- R317 for 5V FAN and R318 for 12V FAN.
- CN23 supports PWM control while CN22 does not support.
PWM FAN Control
- echo 0 > /sys/class/pwm/pwmchip0/export
- echo 10000 > /sys/class/pwm/pwmchip0/pwm0/period
- echo 5000 > /sys/class/pwm/pwmchip0/pwm0/duty_cycle
- echo normal > /sys/class/pwm/pwmchip0/pwm0/polarity
- echo 1 > /sys/class/pwm/pwmchip0/pwm0/enable
miniPCIe slot
currently, miniPCIe slot only support one USB 4G module, example: EC25 when you insert one EC25 module, you may check it.
SFP
After high and low temperature test, the following modules are suppoted by BPI-R3:
4G&5G
- BPI-R3 supports 4G LTE EC25.
- If you want to use 5G on BPI-R3:
1. Insert 5G dongle into USB3.0. 2. Connect RG200U-CN to mini PCIe, connect SoC through USB2.0(speed limited). 3. Make an RG200U-CN LGA adapter board and insert it into M.2 KEY M.
Note: The availability of 4G/5G depends on the local carrier frequency band.
Ap mode on BPI-R3
- ra0 is MT7986a 2.4G wifi
- rax0 is MT7986a 5G wifi
Wifi & Serial cable
- If the chip type of serial cable is pl2303, the driver fails to load the firmware apparently and thus the wifi can't work.
- Other types including cp2102,ch340 and FDTI are all available, serial cable vlotage must be 3.3v LVTTL standard.
UART_TX0 is the Boot Strapping PIN and must be kept low during power-on.
FAQ
- MT7986a Reference Manual for Develope Board(BPi)
TTL Voltage
- The debug-uart TTL is tolerant to 3.3V.
