1Banana Pi/Pro {#bananapi} 2============ 3 4The Banana Pi/Pro is a clone of the well known Raspberry Pi. It has advantages 5compared to the 'old' Raspberry Pi A/B/A+/B+ devices as it is based on the 6Allwinner A20 Dual Core Cortex-A7. It also has 1G Ethernet compared to 100M 7Ethernet on the Raspberry. 8 9There is a lot of effort on Mainline Kernel to fully support the Allwinner 10Chips, for example Fedora 22 Arm will come with support for BananaPi/Pro which 11means that you will be able to have HDMI Output and a number of periperal 12modules work out of the box. 13 14Pin-wise the Banana Pi matches the Raspberry Pi, the Banana Pro has a connector 15similar to the Raspberry Pi A+/B+ 16 17Revision Support 18---------------- 19Banana Pi 20Banana Pro 21 22Interface notes 23--------------- 24 25**PWM** Whilst the Banana Pi is meant to have 1 PWM channel this is currently 26not supported. 27 28**SPI** works fine when used with old 3.4 Kernels provided by Lemaker, on 29Mainline Kernel SPI does currently not work 30 31**COM** I have created devicetree patches so that Mainline Kernel supports all 32COM-Interfaces, this is not yet visible in Kernel 33 34Mainline Kernel requires the use of Device-Trees, mraa tries it's best to guess 35which gpio/serial/i2c/spi is connected where but there is currently no support 36to manipulate the Device-Tree settings from within mraa. If a device does not 37work as expected then please check syslog, mraa usually complains with a 38meaningful message when it is unable to initialize the device. 39 40Pin Mapping 41----------- 42 43This pin mapping refers to the Banana Pi but gives an idea 44as to what the values are from mraa. Note that there is an emum to use wiringPi 45style numbers. 46 47| MRAA Number | Physical Pin | Function | 48|-------------|--------------|-----------| 49| 1 | P1-01 | 3V3 VCC | 50| 2 | P1-02 | 5V VCC | 51| 3 | P1-03 | I2C SDA | 52| 4 | P1-04 | 5V VCC | 53| 5 | P1-05 | I2C SCL | 54| 6 | P1-06 | GND | 55| 7 | P1-07 | GPIO(PI03)| 56| 8 | P1-08 | UART4 TX | 57| 9 | P1-09 | GND | 58| 10 | P1-10 | UART4 RX | 59| 11 | P1-11 | GPIO(PI19)| 60| 12 | P1-12 | GPIO(PH02)| 61| 13 | P1-13 | GPIO(PI18)| 62| 14 | P1-14 | GND | 63| 15 | P1-15 | GPIO(PI17)| 64| 16 | P1-16 | GPIO(PH20)| 65| 17 | P1-17 | 3V3 VCC | 66| 18 | P1-18 | GPIO(PH21)| 67| 19 | P1-19 | SPI MOSI | 68| 20 | P1-20 | GND | 69| 21 | P1-21 | SPI MISO | 70| 22 | P1-22 | GPIO(PI16)| 71| 23 | P1-23 | SPI SCL | 72| 24 | P1-24 | SPI CS0 | 73| 25 | P1-25 | GND | 74| 26 | P1-26 | SPI CS1 | 75 76There is also a second 8-pin connector on the Banana Pi, the pins are as follows: 77 78| 27 | P1-19 | 5V VCC | 79| 28 | P1-20 | 3V3 VCC | 80| 29 | P1-21 | GPIO(PH5) | 81| 30 | P1-22 | GPIO(PI22)| 82| 31 | P1-23 | GPIO(PH03)| 83| 32 | P1-24 | GPIO(PI20)| 84| 33 | P1-25 | GND | 85| 34 | P1-26 | GND | 86
