Maxim +Feather Boards, namely the :adi:`MAX32630FTHR`, :adi:`MAX32650FTHR`, +:adi:`MAX32655FTHR`, :adi:`MAX32666FTHR`, and :adi:`MAX78000FTHR`, +are very small form factors called “feathers”, and they require +special connectors to be used with other Pmod boards. + +This interposer board provides such solution and allows interfacing with +up to two Pmod boards via SPI or I2C interface.
