The Nano Base Board (C) from Waveshare is a compact carrier board for your Raspberry Pi Compute Module 4 (CM4) which includes an 8MP IMX219 camera module alongside a host of other features, great for evaluating the CM4 or prototyping a Compute Module project. Your CM4 simply clicks into the carrier board and can be powered by the USB-C port, which can also be used for programming. You then have access to the other great features of this board: Colour-coded 40-pin GPIO header, Mini-HDMI (4K 30fps), USB 2.0 port for peripherals, DSI port for a DSI display, Micro-SD slot for storage, programmable button and a BOOT selection switch. There are also activity LEDs for both data and power.
