A Feather board without ambition is a Feather board without FeatherWings! This is the FeatherWing 128x64 OLED: it adds a gorgeous 128x64 monochrome OLED plus 3 user buttons to any Feather main board. Comes fully assembled so you can connect the FeatherWing on top of your Feather board and let the board take flight, no soldering required!
