Configuring the Daughter Card for Standalone Use
It is possible to use the daughter cards without the motherboard to run code on the microcontroller.
Power to the daughter cards must be supplied through the terminal power connector ‘J1 – PWR_IN’. It
is required to connect all three voltages (1.25V, 3.3V and 5V) and ground.
Jumpers positions must be moved to allow the J1 to supply the EVB.
J3 must move to position 1-2 (5V_DC_R)
J2 must move to position 1-2 (1.25V_DC_R)
J7 must move to position 1-2 (5V_DC_R)
J5 must move to position 1-2 (3.3V_DC_R)
J4 must move to position 1-2 (5V_DC_R)
