Overview
The Waveshare Nano Base Board (C) is a compact carrier board, technically a compact sized IO board designed for the Raspberry Pi Compute Module 4 (CM4) with dimensions matching the CM4 (55mm x 40mm) boards.
The board features an onboard IMX219-D160 camera module, an 8-megapixel sensor with a 160° field of view, suitable for wide-angle imaging applications.
Equipped with essential interfaces, the board features a 40-pin GPIO header compatible with Raspberry Pi modules. A USB 2.0 Type-A port provides connectivity for peripherals like keyboards, mice, and storage devices. Also, it includes a 15-pin MIPI DSI display port for connecting compatible displays and a mini HDMI port capable of supporting 4K 30fps video output.
For storage, the board includes a MicroSD card slot, making it ideal for CM4 Lite models without onboard eMMC storage.
You can power the board with a 5V DC input via a USB Type-C connector. It has an Onboard LED indicators (PWR and ACK) which provide quick visual feedback on power and activity status. Additionally, the boot selection switch enhances functionality, allowing users to toggle between download and normal operation modes.
The Nano Base Board (C) is a reliable, cost-effective solution for developers and engineers looking to deploy the Raspberry Pi Compute Module 4 in compact, performance-driven applications.
