Screen: hardware upgrade

We are going to have first big hardware upgrade for the driver board. Upgrade from version v7a to v7b and v10a to v10b.

New features and changes:

  1. increase backlight brightness, from approx. 300lu to 400lu.
  2. fit new version 4.3inch screen and later possible new model 4inch screen.
  3. increase stable, solder protect diode directly on board.
  4. increase stable, add write protect signal to eeprom to avoid software mistake write.
  5. change SMT pad size and shape for easy mount on other PCB board.
  6. change SMT pad silkscreen text from “+”, “-” to “DP”, “DM”.
  7. change 8p FPC connector to increase its usage life time.
  8. v10b use purple PCB to avoid confuse with green PCB v7b.
  9. PCB board thickness from 0.8mm to 1mm, increase physics strength.
  10. other small changes to increase USB stable and lower power consume.

Expect new driver boards will come at early of Sep 🙂
