Nano Base Board (C) For CM4

CM4-NANO-C (Raspberry Pi CM4 Ultra Mini Expansion Board Type B) is a motherboard that can be used with Raspberry Pi Compute Module 4. Although small, it can reveal the interface of the Raspberry Pi Compute Module 4 with a built-in camera.

Precautions

1. DO NOT hot plug any device other than USB and HDMI. In particular, electrical installation or removal of the camera is prohibited.

2. Please do not short-circuit the power supply, as the module has no protection.

3. The USB Type-C interface can be used as a power supply or a USB SLAVE interface to program the image.

4. In order to ensure the normal power supply of CM4, please do not connect other devices while using the USB Type-C interface to program the image.

5. Providing 5V 2A to ensure that the CM4 is in normal use. Otherwise, automatic shutdown, frequency reduction, etc. there may be problems.

6. USB2.0, CSI and DSI interfaces are disabled by default and must be enabled by the user.

7. The user key is connected to GPIO21 and pulled to GPIO_VREF by R16 (10K). When the key is not pressed, the GPIO21 is pulled high by default; Pressing the key will lower the GPIO21 level.
