Pepper-V2

V2 pepper PCB test

Changes for Rev-3

  • Replace the SWD and SWCLK on J7 with some I2C and UART capable GPIOs from Pico. The SWD and SWCLK weren't connected in Rev2 the way I thought they would be
  • Replace TMP36 temperature sensor with a TMP235A (similar but cheaper)
  • add ability to turn off SiPM 30V from Pico
  • make test poinst 1.2mm in diameter (were 0.7mm)
  • add logos (woo hoo) and CPERL/CLASSE names
