It breaks out the CM4's key interfaces — HDMI, USB, M.2 NVMe, camera, and GPIO — in a compact form factor with Arduino-style pin headers, bridging the Raspberry Pi and Arduino ecosystems.\n\nThe board includes an onboard ADS7830 8-bit ADC (8-channel, I²C), user-programmable LED, two user buttons, and a micro-SD card slot for CM4 Lite variants. It's powered via USB Type-C at 5V/2A.\n\nKey Features\n\n\nCM4 Socket – Standard connector compatible with all Raspberry Pi Compute Module 4 variants\n\nHDMI Output – Supports up to 4K at 30fps\n\nM.2 NVMe Slot – Accepts 2242 form factor NVMe SSDs for fast storage\n\nUSB 2.0 Port – Host mode (configurable via config.txt)\n\nMIPI CSI Camera Port – Connect a Raspberry Pi camera module\n\nADS7830 ADC – 8-channel, 8-bit analogue-to-digital converter over I²C\n\nArduino-Compatible GPIO – Standard pin header layout for Arduino shields and accessories\n\nMicro-SD Slot – For CM4 Lite variants without onboard eMMC\n\n\nSpecifications\n\n\nPower Input: USB Type-C, 5V/2A\n\nVideo Output: HDMI (4K 30fps)\n\nStorage: M.2 2242 NVMe slot, micro-SD slot\n\nADC: ADS7830, 8-channel, 8-bit, I²C (address 0x48)\n\nUser GPIO: LED (GPIO6), USER1 button (GPIO4), USER2 button (GPIO5)\n\nCamera: MIPI CSI (CAM0)\n\nBoot Switch: ON = USB Type-C (eMMC flashing), OFF = eMMC/micro-SD boot\n\n\nIdeal For\n\nCombining Raspberry Pi CM4 with Arduino shields and peripherals\nEmbedded systems requiring NVMe storage and HDMI output\nIoT gateways and edge computing applications\nCamera-based projects with CM4 processing power\n\n\nPackage Contents\n\n1× CM4-Duino base board\n\n\n\nNote: Raspberry Pi Compute Module 4 is sold separately. A 5V/2A USB Type-C power supply is required — insufficient power may cause throttling or shutdown.\n\n\nResources\n\nWiki Documentation & Setup Guide\n","vendor":"Waveshare","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2318,"title":"Default Title","sku":"WS-21738","price":38.62,"on_sale":false,"in_stock":true,"available_quantity":15,"option1":"Default Title"}]}
