So... can I design a board that directly communicates with the LCD screen? Will I get the power circuitry right? I usually deal only with 5v or 3.3v logic, where most of the power and programming circuits are handled in a board designed by someone else.
Admittedly, I based the design largely off of referencing existing designs, like Sparkfun's ESP32 Thing or Adafruit's 3.2" TFT Breakout. So I can't take lots of credit for this, I mostly just hope I don't mess anything up. It *looks* good.
This new PDA should be much thinner, more reliable (my others always had wires breaking), and will have an ESP32 WROVER, which has extra SPI RAM built in. 5x Faster charging, and a much cleaner/smaller design.
Ordering soon, wish me luck!!!
