The hardware design and features are similar to the LinkStar H28K travel router, but the latter features a 1.5 GHz Rockchip RK3528, while the ROCK E20C is based on a more powerful 2.0 GHz Rockchip RK3528A SoC with the same features and a higher CPU frequency. The ROCK EC20C is also slightly larger, comes with a USB-C port for debugging, and offers more options in terms of RAM/storage configuration.
Software-side, it’s also more versatile with support for Debian with XFCE, Flippy OpenWrt, and iStoreOS, another fork of OpenWrt with a user interface that aims to simplify the configuration process, features the iStore app store for OpenWrt, and also acts as a lightweight NAS software. You’ll find resources to get started, download links for the OS images, and documentation on the wiki.
Radxa sells the Radxa E20C router on AliExpress for $27.88 and up with the final price depending on the selected configuration (and taxes). The 1GB/8GB, 2GB/16GB, and 4GB/32GB models are available on AliExpress, but stocks are limited. Note the power supply is not included by default. You’ll also find the “Mini Network Titan” on Arace Tech, but right now only 1GB and 2GB RAM models are available. Further details may be found on the product page.
