The connection of any power domain to a regulator has to be enabled by a dedicated jumper as
described in Table 9.
Table 9:
MCU power selection jumpers (416DC)
Jumper Setting (* - Default)
1-2: 3.3V from onboard Power SBC
2-3: 3.3V from Mother Board*
1-2: 5V from onboard Power SBC
2-3: 5V from Mother Board*
IO Levels in the Mother
Board - VDD_HV_IO_MAIN
1-2: Select 3.3V

Connect TRNG, Internal RC
oscillator Supply -
VDDA_MISC
1-2: Connect VDDA_MISC to 5V_SR*
Connect SD ADC supply &
Reference –VDDA_SD,
VRH_SD
J7, 1-2: Connect VDDA_SD*
J8, 1-2: Connect VRH_SD*
