The Radxa ROCK E20C is a palm-sized computer designed for use as a router, firewall, or other simple applications. It features two Gigabit Ethernet ports, support for up to 4GB of LPDDR4 RAM and 32GB of eMMC flash storage, a microSD card reader for removable storage, and a few USB ports for power, data, and debugging.
It’s also pretty cheap little device: prices start at $25 for a model with 1GB of RAM and 8GB of storage.
The little computer is powered by a Rockchip RK3528A processor with four ARM Cortex-A53 CPU cores capable of speeds up to 2 GHz and Mali-G450 graphics (although there’s no dedicated video port on this device, so it’s clearly meant to be used for headless applications).
The computer measures 67 x 67 x 15mm (about 2.6″ x 2.6″ x 0.6″) and has an aluminum alloy case and a fanless design. Ports include:
There are also three LED indicator lights on the front of the computer for system, WAN, and LAN status.
Radxa says the E20C can support operating systems including the Debian Linux-based Radxa OS, OpenWrt, and iStoreOS (an operating system designed for network-attached storage devices).
You can buy the Radxa E20C from ARACE or AliExpress. Prices are a little lower at ARACE, but models with 4GB of RAM and 32GB of storage are only available from AliExpress.
