ROC-RK3588S-PC is the first Rockchip RK3588S SBC, supports up to 32GB RAM

Rockchip RK3588S processor, a cost-down version of Rockchip RK3588 SoC with fewer interfaces, has made its way into Firefly ROC-RK3588S-PC SBC (single board computer) about the size of a credit card and equipped with up to 32GB RAM.

The compact SBC also comes with up to 128GB eMMC flash, and offers support for NVMe storage, up to four video outputs through HDMI, USB-C and MIPI DSI interfaces, Gigabit Ethernet, USB 3.0, two MIPI CSI camera interfaces, and more.

Rockchip RK3588S SBC

Software support is the same as for its more expensive big brother, the ITX3358J mini-ITX motherboard, with Android 12.0, Ubuntu Desktop, Ubuntu Server, Debian 11, Buildroot, RTLinux, Kylin Linux, UOS, and others, thanks in part to UEFI boot support.

ROC-RK3588S-PC board should be particularly interesting to people wanting to leverage the higher performance of the Cortex-A76/A55 processor, Arm Mali-G610 GPU, and/or 6 TOPS AI accelerator without paying the premium asked for full-featured Rockchip RK3588 boards. It may not meet the requirements of people wanting high-speed NVMe storage since the RK3588S processor does without the 4-lane PCIe 3.0 found on RK3588, and instead, the board has to fall back to a PCIe 2.0/2.1 interface up to 5 Gbps.

The ROC-RK3588S-PC SBC sells for $219 with 4GB RAM and 32GB eMMC flash, and $299 for the 8GB/64GB combo. That’s quite more than I would have expected with the Rockchip RK3588-powered Rock5 Model B Pico-ITX SBC starting at $129 with 4GB RAM, and $149 with 8GB RAM. A few more details may be found on the product page.
