Description
The Nano Base Board A from Waveshare is a simple, affordable way to evaluate the Raspberry Pi Compute Module 4, breaking out key functionality whilst maintaining a compact and low-profile footprint - the same size as the CM4 itself!
This board allows you to power your CM4 via USB-C whilst also providing a USB port, CSI camera connector, SD card slot, GPIO breakout, boot switch and indication LEDs.
We also stock the Nano Base Board (B) which offers more functionality (but costs a little more).
Note: the GPIO header is packed with the board separately and will require soldering!
Features
The Base Board A is the same overall size as the CM4 module yet offers a host of useful features:
- 40-pin GPIO breakout
- Male colour-coded GPIO pins (packaged separately - requires soldering)
- USB-C 5V power port
- CSI port for Raspberry Pi Camera Modules
- MicroSD card socket for CM4 Lite variants
- 1x USB 2.0 port
- Boot switch
- Power indication LED
- Activity Indication LED
- Dimensions: 55mm x 40mm
