LeMaker Banana Pro

The Banana Pro is essentially an updated version of the Banana Pi. Unlike its predecessor, this device features a microSD ("TF") slot, onboard WLAN and a 40 pin GPIO header (that mimics the Raspberry Pi A+/B+ models). To make room for the additional GPIO pins, the analog A/V output is combined into a single TRRS type 3.5mm connector.

= Identification =

At least 3 different PCB revisions exist. The first pre-production version featured a RTL8189ES Wi-Fi chip instead of the AP6181 used for the production versions. The letters "BANANA PRO" were printed on the bottom side of the PCB. The second batch with AP6181 had also "BANANA PRO" on the bottom between DRAM and HDMI connector. Later batches came without this lettering.

All Banana Pro PCBs are black with yellow expansion headers, and the LeMaker Logo is printed on the upper side of the PCB. The Banana Pro can be differentiated from the other SBCs LeMaker tries to sell starting from June 20th 2015 by looking at the A20 SoC.

Current status
Supported.

Manual build

 * The "legacy" community u-boot-sunxi does not support the Banana Pro. Use mainline U-Boot instead (see below), or try the version from LeMaker's repository.
 * The .fex file can be found in sunxi-boards as BananaPro.fex

Everything else is the same as the manual build howto.

Mainline U-Boot
For building mainline u-boot, use the Bananapro target.

Mainline kernel
Use the sun7i-a20-bananapro.dtb device-tree file for the mainline kernel.

= Expansion Port =

The Banana Pro has a 40-pin, 0.1" connector with several low-speed interfaces.

= Tips, Tricks, Caveats =

FEL mode
The UBOOT button, located next to the three UART pins (J15), triggers FEL mode.

Combined Audio+Video
According to "answer" in http://www.lemaker.org/thread-12417-1-1.html, the pinout of the TRRS connector is (from tip to sleeve) "Left, Right, Video, Ground". This is unconfirmed but would mean it's not the same as on the new Raspberry PIs, and instead would be similar to some MP3players (according to http://www.raspberrypi-spy.co.uk/2014/07/raspberry-pi-model-b-3-5mm-audiovideo-jack/).

= Adding a serial port =



Locating the UART
The UART pins are located in the lower right corner of the board (connector J15) - they are marked as GND, RX and TX on the PCB. Just attach some leads according to our UART Howto.

Powering the board
When no 2.5" SATA disk is used the board can also be powered more reliable through the SATA-power-connector since this connector and the normal power-in Micro USB connector located between SATA and SATA-pwr are connected directly.

= Variants =


 * SinoVoip produced a different version of called "M1Plus" (BPi-M1+) as a Banana Pro rip-off sharing exactly the same hardware specs and almost the same position of onboard connectors. Main difference: SoC, DRAM and PMU are on the upper side of the PCB whereas on the lower on Banana Pro. Featurewise both boards are nearly identical and fex/dts files can be interchanged directly, with one small exception: according to LeMaker's and Sinovoip's fex files, [audio_pa_ctrl] differs: PH26 on M1+ and PH15 on Banana Pro. It turned also out that the blue led is red and connected to PH25 instead of PG02.
