Connect controller main base board with any other module function board easily. Use board to board plug-in connector, just plug in in one second, no need any wirings or soldering works.
Middle connectors are special types, FB (female/base) type connector on base board, and MM (male/module) type connector on module board.
Each connector is 12pin, include uart / I2C / SPI and power supply pins, you can find common pin definitions here.
