Configuring the 516 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 JP3 – EXT PWR. It
is required to connect all three voltages (1.25 V, 3.3 V, 5V SR and 5 V LR) and ground as explained in
Section 5.1.2
(or)
The Daughter Card can be used in standalone by enabling PowerSBC with its respective jumpers as
described in the
Section 5.1.3.
Additional to enabling PowerSBC power supply it is required to connect the 5V_SR power rail to the
Analog power rail of the daughter card that powers the VDDA_SD & VDDA_EQ (ADC supply) and
VRH_SD, VRH_SEQ (ADC reference voltage) pins. It is recommended to do that by installing a
jumper connecting J5 (2-3) (5.0V_SR) to Analog Supply Rail.
