...

  •  Verify the 48V outputs can be enabled and disabled via N-CH FET (can draw load from the output when enabled, can’t otherwise)
  •  Verify the analog output of the amplifier matches expectations

5V Power:

  •  Power onboard + touch test, verify components and the board itself does not get too hot
    •  5V_1
    •  5V_2
  •  Verify all ICs, details, LEDs, etc. are powered on successfully. Communicate with all peripherals
    •  5V_1
    •  5V_2

STM:

  •  Verify the enable pins can be driven high and low (PC14, PC11, PB9, PD2)
  •  Verify the STM can read the state of the OC pins accurately (PC13, PC12, PC10, PB8)
  •  Verify the analog reads of both of the 5V rails (PB7, PC15)
    •  Both of the pins for this are not analog capable, but was able to read from a peripheral

Electrical

  •  Verify enable condition on all 4 switches (can draw load from the output when enabled, can’t otherwise)
  •  Verify output current limit (2.4A)
    •  The current limit is actually 2A not 2.4A
    •  Verify the OC pin goes low in this condition

...

  •  Verify the 17V output can be enabled and disabled vis N-CH FET (can draw load from the output when enabled, can’t otherwise)
    •  N-CH footprint has source and drain pins reversed
  •  Verify the analog output of the amplifier matches expectations
  •  Verify the TVS diode function protects against an oversimplification of signal
