MYiR Tech provides a Linux 5.10.83-based image built with the Yocto Project and plans to release Ubuntu and Debian images soon along with open-source drivers. Usually, they only do that for their paying customers, but the Yocto image for the Remi Pi, some documents, and source code can be downloaded directly on the MYiR website. Chinese readers may also access a support forum that looks to be somewhat active.

Potential applications for the Remi Pi and associated MYiR MYC-YG2L23 CPU module include industrial control systems, medical equipment, instrument displays, charging piles, industrial gateways, and energy storage EMS systems. MYiR sells a Remi Pi kit for $55 which you’ll find along with other information on the product page. For reference, the company is also selling the Remi Pi for 198 CNY on TMall, or about $27.5 US~~, so a price around $29.99 plus shipping might be feasible for users out of China~~.
