The BPI-M3 is an Allwinner A83T based SBC in the Bananapi/Bpi family.
It is roughly the same form factor as the BPI-M1+, with roughly the
same peripherals and connectors:
- 2GB LPDDR3 DRAM
- 8GB eMMC
- Micro-SD card slot
- HDMI output
- Headset (stereo + mic) jack
- Onboard mic
- Gigabit Ethernet with RTL8211E transceiver
- Ampak AP6212 WiFi + BT
- USB OTG connector
- USB-to-SATA bridge connected through a USB 2.0 hub
- Consumer IR receiver
- MIPI DSI LCD panel connector
- Camera interface (parallel and MIPI CSI) connector
- 3 LEDs (Red, Green, Blue), of which 2 are controllable (GB)
- Raspberry Pi 2 compatible GPIO header
