Board acceptance test

Setting up the test

• Turn the current off on the DC supplies before connecting the board, otherwise the spark might murder the DC/DC converter on the board
• The correct order:
  • Make sure crocos are disconnected
  • Give a little current
  • Set up the desired voltage
  • Turn off the current
  • Connect the crocos
  • Give a little current
• Use the special yellow 1k pull-up banana-to-croco wire for the 5V!

Evaluating the test

• The current must be jumping up and down, the current must never exceed 800 uA
• The oscilloscope must be able to decode the UART
• Press the button: all 4 LEDs must come on
• Write down
  • The current
  • That the LEDs are OK
  • That the UART is OK
