Description
CardKB HAT is an implementation of a full-featured QWERTY keyboard tailored as a HAT for the M5StickC. Consider that you want to make some cool stuff that require interaction through typing on a keyboard. But M5StickC itself just has 2 buttons. So, here comes the flexible and yet powerful “CardKB HAT Inch to solve the issue.
The CardKB HAT also offers support for several button combinations (Shift+Key, Fn+Key) adding virtually many different keys. This comes with an RGB LED to indicate the keyboard state. IIC address is 0x5F.
