It includes an onboard 8MP camera and breaks out the module&#039;s interfaces.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL23451 WSAL23451 – Nano Base Board (C) for Raspberry Pi Compute Module 4, Same Size as the CM4, Onboard 8MP Camera]<br /> <br /> == Technical overview ==<br /> * The board is a mini expansion board (Type B) for the Raspberry Pi CM4, sized like the module.<br /> * It has a MINI HDMI port supporting 4K/30fps output.<br /> * DSI and CSI interfaces are disabled by default and must be enabled via device-tree files.<br /> * The USB2.0 port is also disabled by default; enable it by adding dtoverlay=dwc2,dr_mode=host to config.txt.<br /> * A user button is connected to GPIO21 and pulled up via R16 (10kΩ); pressing the button pulls the signal low.<br /> * A micro SD card slot is present but only usable with the Lite version of the CM4.<br /> * Two status LEDs indicate power (PWR) and operating state (ACK) of the CM4.<br /> * A BOOT switch selects between USB Type-C (download mode at power-on) and USB Type-A (boot from eMMC or SD card).<br /> <br /> &#039;&#039;&#039;Commands and examples – verify before use:&#039;&#039;&#039; <br /> &lt;syntaxhighlight lang=&quot;text&quot;&gt;<br /> sudo raspi-config<br /> raspistill -o image.jpg<br /> raspivid -o video.h264 -t 10000<br /> libcamera-hello --list-cameras<br /> libcamera-hello -t 0<br /> libcamera-jpeg -o test.jpg<br /> libcamera-vid -t 10000 -o test.h264<br /> sudo dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob-disp1-double_cam.dts<br /> sudo rm -rf /boot/dt-blob.bin<br /> sudo reboot<br /> &lt;/syntaxhighlight&gt;<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/CM4-NANO-C CM4-NANO-C - Waveshare Wiki]<br /> * Source revision: 89040<br /> * Captured: 2026-09-04T02:59:25+00:00<br /> * SHA-256: &lt;code&gt;26c145b40ed91dc61140699a4a781034a6817309c166ec601eb07afb0e945110&lt;/code&gt;</div>
