GenBook RK3588 is a modular Linux (and Android) laptop powered by a Rockchip RK3588 Arm system-on-module (SoM), and easily serviceable by the user who can add M.2 MVMe SSD storage, switch wireless module, and eventually update to a more powerful SoM, or even change the display.
It looks very similar to the Cool Pi Arm Linux laptop, and it’s indeed made by the same company, but a representative told CNX Software that the GenBook RK3588 was an upgrade of the Cool Pi without further details. So let’s have a closer look.

The main differences against the original Cool Pi laptop are that the system-on-module module now comes with LPDDR5 memory instead of LPDDR4/4X memory, a slightly brighter display is used (300cd/m2 vs 250cd/m2) and there’s a 50-pin FPC connector for expansion such as 5G and other future boards/modules with PCIe, SATA, USB, GbE, and/or other interfaces as listed in the specifications.
The company will provide Debian 11 (default), Ubuntu 20.04/22.04/24.04, Armbian, Android 14, UOS, KylinOS, and Alt-Linux images for the laptop. Cool Pi/Open SBC/Shenzhen Tianmao Technology (three names for the same company) will eventually provide documentation on the wiki including OrCAD and PDF schematics for the mainboard, PDF schematics for the SoM, and OS images. They’ve actually done that on the Crowd Supply, but the OS images are behind an account-protected Onedrive share… You can also get some support on the English/Chinese forums and download the OS images from Baidu (usually slow outside of China).
Shenzhen Tianmao Technology has launched the GenBook RK3588 on Crowd Supply with a $60,000 funding target. They have no backers right now, likely because the value proposition is not amazing with the model with 8GB RAM and a 64GB eMMC flash going for $500, and the 32GB RAM + 1TB SSD for $700 including worldwide shipping. Backers will also need to be patient as the RK3588 laptop is only scheduled to ship by the end of April 2025.
