5. Interfaces

5.1. J1 Interface

The J1 interface includes power, control, and MIPI signals connection to EVDK.

5.2. External Power Supply Connections

The J5, J7, and J8 headers allow external power supply connection to the sensor board. Using a jumper to short pin 1
and 2 of the J7 header supplies 1.8 V from J1 connector. Using a jumper to short pin 1 and 2 of the J8 header supplies
2.8 V from J1 connector.
To use external supplies, use pin 1 of these headers. Note that 3.3 V supply for IR_CUT circuit is not provided through
J1.
