14.5 TF Card
It is strongly recommended that use the power source NVCC_SD2 output from J2.36 to power the
memory card, and NVCC_SD2 DO NOT use to power other devices. The voltage level of NVCC_SD2
can be changed through software to support the high speed mode. Note that maximum current
output is 150mA. Do not exceed 150mA at any time to avoid any unpredictable failure.

14.6 SOM Power-Up Enable
Suggest that using J2.60 (GND) on SOM to enable the 5V power supply for SOM as the following
demo circuit. There will be no 5V power supply from the BTB connector on Baseboard while no
