PCB designs and eCAD files for the "You Don't Have to Like All the Art!" project.
This system consists of two distinct circuit boards:
lta-logic-module - The "logic" that determines when it's dark out / should be active, what messages to light up on the sign, manages PWM or other effects when displaying the sign, and also handles button inputs from users. Runs on a combination of 5V and 3V3. This is designed around a port for installing an Adafruit Feather M4 Express (ATSAMD51 / Cortex-M4) Arduino…
