3.4 Carrier Board Introduction
Note: components tag with marks of ‘_DNP’ means the components are not soldered.
3.5.1 Power
The carrier board is equipped with a DC12V power adapter. S1 on carrier board is the power key, and it is designed with
TVS, and over current protection by F1, D1 together with F1 for anti-reverse operation.
