The company provides Android 13, Debian, Ubuntu, and ROS all of which can be found in their GitHub repository. However, after looking for a while, I couldn’t find much documentation or a Wiki page for the board, so the status of the documentation is about the same as when we wrote about Rockchip RK3566/RK3568-powered LucanCat SBCs last year. Another concern about the board is its lack of a heatsink or fan; so far, the company has not provided any updates on this issue.
Previously, we’ve talked about similar SBCs like Youyeetoo R1, Indiedroid Nova, and 9Tripod Pico Pi V2.0, all of which use an SD card for storage. But this is the first time we’ve seen a Raspberry Pi-sized board powered by Rockchip RK3588S that includes a SIM card slot.
You can buy the EmbedFire LubanCat 4 card computer on several shops on Aliexpress where the “4GB RAM + NO EMMC” version starts at $104.27, and the 16GB + 128GB version goes for $173.22 and up.
