Making the controller board PCB
While the enclosure was printing, I set about designing the controller board for the LCD.
It’s really little more than an AVR chip with the diode and resistor from the earlier piezo schematic, a decoupling capacitor (to provide a steady supply voltage) and a 4-pin connector to join it to the LCD pins.
The whole thing fits onto a tiny PCB smaller than the actual LCD controller board, so I’m pretty confident that everything is going to fit inside the enclosures…
