We've reported on numerous single-board computers here at Notebookcheck, with the Raspberry Pi 5 probably being the most popular representative of this category. The Raspberry Pi is also available as a Compute Module, which is essentially more compact and can be used with a specially designed circuit board, but does not come with the connections typical of a single-board computer.
The ArmSoM-CM1 is another single-board computer that can be used with such a carrier board, but the board itself already has various connectors. These include MIPI DSI with two lanes for image output, a USB-C port for power supply, and a microSD card slot. Two GPIO headers are also available, one with 44 pins and one with 40 pins. The computing chip is an RK3506J SoC with three Cortex-A7 cores and one Cortex-M0 cores, supported by 256 or 512 MB of NAND storage and 256 or 512 MB of DDR3L RAM. As for dimensions, the board measures 70 x 42 millimeters.
The single-board computer is also offered with a CM1 IO hardware interface, an expansion board which measures 100 x 70 millimeters and comes with two additional USB 2.0 ports. Further features include two Ethernet ports with a maximum data transfer rate of 100 Mbit/s, WiFi 5, and Bluetooth 4.2. The CM1 board itself is available for $15, while the kit with the expansion board costs $28.50. Shipping costs and times depend on the buyer's location.
