Greylock is a custom macropad built for fun: keys, LEDs, a rotary encoder, and an OLED, each programmable to any input or script, driven by a KB2040 microcontroller.
First attempt at an SMD PCB — next time skipping the FPC connector to the OLED, since dragging solder across that pitch took more than one try.
Housing went through a few shapes before landing on a “calculator” look; mounting the OLED to the case instead of the board below it made a slim top face harder to pull off.
