BigTreeTech recognized primarily for its 3D printing equipment, has launched a Raspberry Pi CM4 (opens in new tab) various board. The machine, as reported by CNX Software program (opens in new tab), makes use of the very same type issue because the Compute Module, however downgrades the specs. Nonetheless, in the event you’re after a low-power board for IoT or different product that wants the type of IO a CM4 can present, this seems like an inexpensive substitute.
There’s additionally a service board that turns it right into a full-fat Pi 4 B-style (opens in new tab) board, however the precise specs look weak compared to the actual factor. You get an Allwinner H616 quad-core Cortex-A53 SoC working at 1.5GHz, a Mali-G31 MP2 GPU and a single gigabyte of RAM. DDR3 RAM, at that. It’s not an important comparability to the tiny powerhouse that’s the Pi 4, however it is likely to be sufficient for a NAS or different low-power computing undertaking.
The CB1 will decode video as much as 4K/60 and show it by way of a single HDMI port on a service board. It may possibly talk utilizing Wi-Fi 4, or 100Mbps Ethernet by way of a service, and there are two board-to-board connectors shut sufficient to these on the CM4 to make it appropriate with equipment made for the extra highly effective module. It measures 55 x 40 x 4.7mm – the identical as, you’ve guessed it, the CM4.
There’s good software program assist too, with a picture of Debian Linux out there to obtain from GitHub (opens in new tab). It’s a model of Bullseye, the distro that powers the official Raspberry Pi OS, and makes use of kernel 5.16, so isn’t notably outdated, although the chipset is supported within the new 6.0 Linux kernel (opens in new tab).
Efficiency must be just like the Raspberry Pi 3, which was by no means launched within the CM4’s type issue, as an alternative showing as a DIMM-like board with a broad edge connector. The CB1 is on the market from the Biqu retailer (opens in new tab) in a bundle with the Pi adapter for round $40. It has but to seem on BigTreeTech’s AliExpress retailer (opens in new tab).
