Precautions for Using Mini Base Board for RPi CM4
- The board has a DSI0 display interface, not DSI1.
- The FAN supports only 5V fans. It is not compatible with a 12V fan.
- Before burning the image via the Type-C interface, make sure to disconnect the devices so that the power supply for CM4 does not fluctuate.
- The Type-C interface supports power supply and image burning (as USB SLAVE)
- Weight: 49 grams
- Dimensions: 85 x 56 mm | 8.5 x 5.6 cm
