Datasheet
Power consumption
The following table lists the power draw for certain SoM components during different operational tests.
Tested with Coral Dev Board—performance on your custom baseboard may vary
During the high performance test, the top power-consuming components (top heat sources) are indicated in figure 4.
Version 1.2 (August 2019)
Name Type Connector Pins Voltage Description
VDD_3V3 Power J1310 94, 96, 98 100 3.3V 3.3V output from SoM.
Can be left floating if not
used. Not for high-current
usage; can be used to pull-
up GPIO.
VDDA_1V8 Power J1310 91, 93, 95, 97, 99 1.8V 1.8V output from SoM.
Can be left floating if not
used. Not for high-current
usage; can be used to pull-
up GPIO.
POR_B Output J1310 79 3.3V "Power_On_Reset" signal
from IMX8M PMIC to reset
the SoC (active-low open-
drain output)
SYS_nRST Input J1312 63 3.3V System reset (active-low
input). Recommended for
reset button on
baseboard.
