Tildagon Badge Hexpansion by Skyler84
The Goosepansion hexpansion is a capacitive touch addon for the Tildagon badge. Additionally it is designed to be reversible - it can be inserted in either orientation to alter the behaviour of the hexpansion!
The hardware of the original Goosepansion had some issues with the active electronics. This is being investigated and a bodge fix will hopefully be released soon!
The goosepansion contains some active electronics that are supposed to allow it to be inserted in either orientation. This is achieved by switching two pairs of pass-fets acting as level shifters and should allow the I2C bus to work in either orientation. This had some issues in the original board which is being tested and updated.
