7mm Trackball MX Switch Daughterboard
« on: Sun, 18 October 2020, 05:22:18 »
I was fooling around in kicad today and made this small board to allow the 7mm trackball by BTO https://bit-trade-one.co.jp/selfmadekb/adtb7m/ to be connected to an Arduino via a level shifter. It comes with through-hole positions for MX and Alps switches as well as for rotary encoders and can be placed in the position of a switch or rotary encoder and connected with diode legs or whatever. If connected using the pins for an encoder, it allows for the use of the encoder A, B and GND connections for the serial interface of the trackball. If anyone is interested, I can give it a proper name and upload the files to Github.

Based off this https://github.com/sekigon-gonnoc/LevelConverterForTrackballModule

A trackball in place of a switch?  That's genius, assuming they're actually good.

As homing bump of key caps, the module is little bit, around 5mm taller than I think.
