The Radxa Rock 3A is a credit-card-sided single-board computer with a 2 GHz Rockchip RK3568 quad-core ARM Cortex-A55 processor, Mali-G52 graphics, and a neural processing unit.
It looks a bit like a Raspberry Pi and has some similar features including a 40-pin GPIO header and USB and Ethernet ports. But Radxa’s little computer stands out in a few ways. It support san optional eMMC storage module. And it has two M.2 keys – one for wireless cards and another for PCIe NVMe solid state storage.
Radxa says the Rock 3A will be available for purchase starting in August, with prices ranging from $35 for a model with 2GB of RAM to $75 for an 8GB model.
All models will have the same basic features set including:
- Processor: Rockchip RK3568
- RAM: 2GB, 4GB or 8GB of LPDDR4-3200 memory (DRAM controller frequency up to 1560 MHz)
- Storage: Pluggable eMMC module, M.2 key for PCIe 3.0 x2 NVMe SSD (on the bottom), microSD card reader
- USB-C: 1 x USB-C for power delivery
- USB-A Ports: 2 x USB 3.0 (1 x OTG and 1 x Host) and 2 x USB 2.0
- Connectivity: Gigabit Ethernet with PoE support and M.2 E key for PCIe 2.0 x1/SDIO/UART with support for WiFi cards
- Display: HDMI 2.0 and MIPI DSI
- Other connectors: 40-pin GPIO header and MIPI-CSI camera connector
- Dimensions: 85mm x 54mm (3.3″ x 2.1″)
The system can also be configured to support SATA storage by using a breakout cable connected to the two USB 3.0 ports.
Radxa says the Rock 3A will support the Debian 10 Linux for Rockchip-powered devices that’s maintained by the Toybrick team, but it’s likely that other operating systems will be ported to the platform as well.
