These 128x32 OLED screens are compatible with keyboards like the Corne, Lily58, and Helix PCBs.
Each OLED screen comes with a 4 pin socket and diode legs which can be used to socket the OLED screen. The socket height sets the OLED screen slightly above a Mill-Max socketed pro micro. The headers that come with the OLED screen cannot be used with the 4 pin socket. They are too large to fit in the holes. You must socket the OLED screen with diode or LED legs in order to be used with the 4 pin socket.
Displays are available in screen text in white or blue.
