The Allwinner D1 (opens in new tab) RISC-V processor has turned up again, this time forming the core of the $17 LicheeRV from Sipeed, a tiny computer module with a curious form factor, as spotted by CNX Software.

Measuring just 46.2 x 25mm, the board sees the CPU, running at 1 GHz, backed by 512MB of DDR3 RAM. It looks rather like a RAM stick itself, in the vein of the older Raspberry Pi (opens in new tab) Compute Modules (opens in new tab), but those aren’t SODIMM connectors you can see down the edge of the board - it’s two sets of 67-pin M.2 B-key connectors. 

These are built to slot straight into a docking board that will supply additional connectivity, such as HDMI, Ethernet, MIPI DSI  and GPIO access. You could use the board as it is - there's a micro SD slot, a USB-C port for power, and if you opt for the more expensive model, an extra $5, you can add a 1.14in magnetic SPI display.

Docking boards should be with us next month, according to Sipeed’s Twitter account, along with a version with GPIO pin support. Compatible operating systems include Tina and Debian Linux, and the LycheeRV is available from AliExpress now (opens in new tab).
