Gary PengKnobo v1.0 (Made on 6/3/18)
My first time designing and manufacturing a PCB. It was running on a Teensy 2.0 with Teensyduino firmware.
Knobo v2.0
Knobo now uses SMT components and a Atmega32u4 microcontroller.
The PCB of Knobo v2.0 didn't work due to some design flaws :(
It was also my first time doing SMD soldering, It took me 3 tries and 3 wasted chips before I managed to solder the Atmega32u4.
Knobo v2.5
Removed one of the keys to make the whole thing more compact.
