PinDefinitions of Extensible connector
Banana Pi has multiple extensibleconnectors for users to develop their own amazing projects andapplications. Most of common extension accessoriesIncluding LCD panel, touch screen, camera module, UART console and GPIO controlpins are accessible from Banana Pi on-board connectors and headers.
BananaPi extensible 26-pins GPIO headers
Banana Pi has 26-pins GPIO headers toextend the functions such as I2C, SPI, 5V and 3.3V output…etc. There are also additional GPIO pinsavailable for extension controls and daughter boards. For instance, you can use those headers toconnect an Arduino board for your projects. Here could be the start point for your way of exciting applications.
CON3(GPIO Headers)
CON3 is a DIP-26 headers. The header pin definitions of CON3 are shownas below.
You can connect the headers for I2C, UART,SPI connections. The 5V and 3.3 V poweroutput are also available here. Meanwhile, there are several pins free for GPIO pins for your specificusage.
