PROCEDURE
7.1.0
Check Continuity
Ensure there is nothing connected to the EVM.
Remove the jumper from P16. Check continuity between pin 1 of header P9 and Pin1 of J1 (Red VCC
connection) with the multimeter. Test passes if there is no continuity.
Keep Jumper removed for the rest of testing.
7.2.0
Test Voltage
Connect the negative lead of the multimeter to J2 or one of the four GND headers (P3, P4, P5, P6).
Connect the positive lead to test point P11. Test passes if Voltage measured is between 0 V and 0.2 V.
7.3.0
Test Voltage 2
Apply 3.3 V from the same power supply powering the board to Pin 8 of header P9(indicated below).
Connect the negative lead of the multimeter to J2 or one of the four GND headers (P3, P4, P5, P6).
Connect the positive lead to pin 4 of U3. Test passes if Voltage measured is between 6.7V and 7.3 V.
Keep the 3.3 V applied to Pin8 of header P9.
7.4.0
Test Voltage 3
Without removing the 3.3 applied to Pin8, connect the negative lead of the multimeter to J2 or one of
the four GND headers (P3, P4, P5, P6). Connect the positive lead to test point P11. Test passes if
Voltage measured is between 0 V and 0.2 V.
Keep the 3.3 V applied to Pin8 of header P9.
7.5.0
Test Voltage 4
Without removing the 3.3 applied to Pin8, apply 3.3 V from the same power supply powering the board
to pin7 of P9(indicated below).
