It follows the CM5's two 100-pin connector form factor but is only partially electrically compatible, lacking dual HDMI, standard MIPI camera/display support, and running muxed PCIe with USB 3.0. It supports Debian-based Walnut Pi OS, Ubuntu, Android, and Home Assistant rather than Raspberry Pi OS. Pricing ranges from $28 to $49 depending on configuration, with an optional IO board and enclosure bundle, undercutting the roughly $97.50 equivalent Raspberry Pi CM5 module. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the Walnut Pi CM2 and how does it compare to the Raspberry Pi CM5? The Walnut Pi CM2 is a Raspberry Pi CM5-compatible compute module using an Allwinner T527 octa-core Cortex-A55 SoC instead of the CM5's Broadcom BCM2712 quad-core Cortex-A76, making it less powerful but cheaper. It offers up to 4GB LPDDR4 RAM, up to 128GB eMMC, WiFi 6, Gigabit Ethernet, and a 2 TOPS NPU, priced $28-49 versus about $97.50 for an equivalent CM5 module. _Compare compute module specs and pricing trade-offs like these before picking hardware for your next embedded project on daily.dev._ ### Can I run Raspberry Pi OS on the Walnut Pi CM2? No, Raspberry Pi OS cannot be installed on the Walnut Pi CM2 since it uses an Allwinner T527 SoC rather than Broadcom silicon. Instead, the module supports Debian 12-based Walnut Pi OS, Ubuntu, Android, and Home Assistant, with OS images and setup instructions available through the vendor's wiki. _Track OS and hardware compatibility details like this before committing to a compute module by following daily.dev._ ### Is the Walnut Pi CM2 fully pin-compatible with Raspberry Pi CM5 carrier boards? No, compatibility is only partial. The module supports just one HDMI 2.0 output instead of the CM5's two, its MIPI DSI and CSI interfaces typically won't work with official Raspberry Pi cameras and displays, and its PCIe Gen2 x1 lane is multiplexed with USB 3.0, so the pinout must be checked carefully against any specific carrier board. _Check hardware compatibility caveats like these before designing around a Raspberry Pi form-factor alternative, a task daily.dev supports._ ## Similar posts on daily.dev -
