Expert Summary

The Radxa ROCK Pi E is a curious, but fairly capable little SBC. Packing a 4-core Rockchip RK3328 CPU, along with 2 RJ45 Ethernet ports (albeit 1x 100Mbit, and 1x1Gbit, the latter supporting PoE via their HAT) it could make a great little appliance. Performance is what you'd expect from an SoC at this level, but overall, for $30, it's not too shabby.
