Quadruple-check power supply

From README FIRST: How to Request Troubleshooting Help For WTPA2 / Post a Bug Report:

*Does WTPA power up?
*ARE YOU SURE your cables are hooked up right?

Todd said -- I finished mine, it wouldn't power up, and I had
ABSOLUTELY CONFIRMED that I was getting power to the board.
Triple-checking didn't help, but quadruple-checking revealed that I had a
center-negative power connector, not center positive, and had been
measuring voltage on the board backwards. Three times. Thanks for the diodes!


  • Center positive and 2.1mm female guitar pedal/Roland type (whatever...) as the sex and size of the jack for the AC/DC adapter/wall wart/power supply could be included in the manual? I missed it in the bom.
