Froggy75
A 75% hotswap PCB through-hole style that utilises two EC-11 rotary encoders and an Elite-C daughterboard – by flehrad.
Published July 12, 2021
Talking in this week's episode of The Board [from 12:11] podcast Don introduced Froggy75, a layout (concept sketch) by Lara Rath and PCB designed by Don Chiou (u/flehrad) himself.
This board is a 75% hotswap through-hole style that utilises an Elite-C daughterboard and two EC-11 rotary encoders – in the position of eyes. The source files are available on Github.
The QMK for this board is currently undeveloped, however the schematic is provided in this repository for firmware development.
Please note that to fit the board layout and unique encoder pins, a duplexed matrix was utilised to conserve sufficient pins for the 24-pin limit on the Elite-C.
This gerber is open source for use, please attribute/acknowledge accordingly if used.
This PCB is UNTESTED and not yet confirmed to work correctly, produce at your own risk.
