EmbedFire LubanCat 4 card computer - A Rockchip RK3588S dev board with a mini PCIe socket for WiFi or 4G LTE

Launched by Yehuo Electronic EmbedFire LubanCat 4 card computer or LubanCat 4 in short, is a Rockchip RK3588S SBC that packs quite a lot of features in an 85x56mm form factor with Ethernet, USB, mini PCIe, HDMI 2.1, SIM & microSD card holder, and more.

The board comes with up to 16GB of RAM and 128GB of eMMC flash. It comes with a Gigabit Ethernet port, five USB ports (including one USB-C), a built-in microphone, multiple audio inputs and outputs, a 40-pin Raspberry Pi compatible expansion header, and supports HDMI input through an adapter connected to a MIPI CSI port.

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.
