FPD1: GPIO expanders both work

• flash smoke_pca9539r with I2C address 0x74

• ensure all the LEDs on the board light up for that gpio expander

• repeat for 0x76

• if unsure, repeat for 0x76 and make sure between the two of them all the LEDs light up

FPD2: All BTS7200 Isense works

FPD3: Reading SPST pot works

FPD4: Fan control works

FPD5: Voltage regulator works

FPD6: UV detector works

PS1: Valid pins work

• flash power_select

• connect all 3 power supplies

• turn off and on each power supply until you’re sure the valid pins being logged on minicom work (should be 1 for on, 0 for off)

PS2: Vsense works

• repeat setup for PS1

• for each power supply, vary the voltage from 12V-13.5V and make sure the voltage logged for that power supply is reasonably accurate (+/- 100 mv is ok)

PS3: Isense works

• repeat setup for PS2

• connect an e-load to the output and set it to constant resistance mode, around 30 ohms

• for each power supply, vary the e-load resistance such that the current drawn swings between 300 mA and 1000 mA

• verify that the current readings are reasonably accurate (+/- 100 mA is ok)

PS4: Switching supplies works

• repeat setup for PS1

• switch to and from each power supply to verify that every switch direction works

PS5: All temp sense works

PS6: Reading aux switch works
