Power supply

The ROCK 3 is powered by Type-C port and has a wide range of input voltage, from 9V to 21V. ROCK 3 supports USB Type-C PD 2.0 with 9V/2A, 12V/2A, 15V/2A and 20V/2A. Besides, the Pi supports QC 3.0/2.0 with 9V/2A and 12V/1.5A. The Type-C cable you using needs to support data communication. We call it USB Type-C charging data cable.

Short-circuit the FSPI_CLK pin and GND pin to make SPI Nor flash unavailable.

Please note that you should short-circuit pin#1 and pin#2 always when spi nor flash is not used. Like the yellow left hat.
