The Rock Pi S is now available to purchase from US$9.90 with up to 512 MB of RAM and 1 GB of NAND flash storage
It has been a few months since we covered the Rock Pi S, the tiny SBC developed by Radxa. The board features a Rockchip RK3308 SoC that integrates four ARM Cortex-A35 cores and can clock up to 1.3 GHz, along with either 256 MB or 512 MB of RAM depending on the model you buy. The SBC runs on 5V, which can be supplied via its USB 2.0 Type-C port or its 26-pin GPIO header. There is another 26-pin header designed for audio expansion.
Radxa has also integrated a microSD card reader, IEEE 802.11 n Wi-Fi, Bluetooth 4.0 and a USB 2.0 Type-A port. The board supports 100 Mbps Ethernet too, but you will need an additional HAT for this functionality. Likewise, you will need an external antenna for Bluetooth and Wi-Fi connectivity, which CNX Software has confirmed does not ship with units sold by Seeedstudio.
The Rock Pi S supports Debian Linux and Buildroot, details of which you can find in the corresponding wiki. The board comes with either 256 MB of RAM for US$9.90, US$13.90 for 512 MB of RAM or US$23.99 for 512 MB and 1 GB of NAND flash storage. Seeedstudio will start shipping units on November 12 and is taking pre-orders now.
