Radxa’s Rock Pi S is a tiny computer that’s less than half the size of a Raspberry Pi Model B. With a starting price of just $9.90, it’s also less than a third of the price.
But this single-board computer is also aimed at folks who are willing to forego some of the usual goodies… like no GPU, DisplayPort, or HDMI output.
You could use the Rock Pi S as a headline computer for IoT and/or voice applications.
While the $9.90 version has just 256MB of RAM and no built-in storage, some higher-priced configurations have up to 512MB of RAM and up to 8GB of embedded NAND flash storage.
- microSD card reader
- USB 2.0 Type-A port
- USB 2.0 Type-C port for power and/or data
- 10/100 Ethernet
- 26-pin GPIO headder
- 26-pin voice/audio header with SPDIF, I2S, PCM, TDM, PDM, and HDMI ARC
There’s also optional support for 802.11b/g/n WiFi and Bluetooth 4.0 with an external antenna and/or a Power over Ethernet HAT.
Unlike a Raspberry Pi mini computer, which is arguably designed for developers and ordinary computer users alike, the Rock Pi S is clearly aimed at folks who know what to do with a headless computer that lacks a display.
I mean, technically you can connect a display — the Rock Pi S does have limited support for a Waveshare 3.5 inch LCD which connects to the SPI2 pins on the Rock Pi S if you need a display, but there’s no 2D or 3D graphics acceleration do don’t expect much in the way of graphics. So this is really a mini PC aimed at developers, makers, and other folks in the market for a tiny, cheap, IoT computer.
Also, it’s kind of cute… mostly because it’s just so tiny.
