Firefly is working on a Rockchip RK3588 Mini-ITX (ITX3588J) motherboard


After Radxa ROCK5 Pico-ITX SBC and Banana Pi RK3588 SoM and devkit, the Firefly ITX3588J mini-ITX motherboard is the third hardware platform we’ve seen with the Rockchip RK3588 octa-core Cortex-A76/A55 processor.

The board will be interesting for people wanting a PC or Arm workstation as the mini-ITX form factor will allow the board to be installed in a standard case, and there are plenty of resources and I/O with up to 32GB of RAM, four SATA ports, multiple 8K/4K video outputs and inputs, dual Gigabit Ethernet, WiFI 6 and Bluetooth 5.0, one PCIe 3.0 x4 slot, and more.

RK3588 mini-ITX motherboard

The company will provide Android 12.0, Ubuntu Desktop, Ubuntu Server, Debian 11, Buildroot, RTLinux, Kylin Linux, and UOS for the board. The large number of supported Linux distributions is certainly helped by the UEFI bootloader provided for the card. Note that the CPU, memory and flash storage are all on a system-on-module, so it should be easy to upgrade/downgrade the module’s memory/storage as needed.

The company was also one of the first to launch a Rockchip RK3399 board in 2016 with the Firefly-RK3399 SBC, and compared to the previous platform, the Rockchip RK3588 processor is said to be up to four times faster, while the GPU performs up to 8 times better, and the AI ​​performance delta should even be higher since the RK3588 comes with a 6 TOPS NPU. That’s roughly what we reported with early RK3588 benchmarks, though Firefly rounded the number, and graphics performance varies a lot depending on workload.

Rockchip RK3588 mini-ITX board

The Firefly ITX3588J mini-ITX motherboard is still in the works, and we don’t have information on availability and pricing. That said, we were told that the CPU and PMIC combo retails for $60, so such hardware will likely cost between $200 and $300 depending on the options. More details can be found on the product sheet.
