In the past, we have seen some Rockchip boards from Radxa, like the Rock pi N10(RK3399Pro) and the Rock PiS powered by the RK3308 Cortex-A35 processor. Now, Radxa has launched a Rock Pi E SBC, which is a Rockchip RK3328 based SBC. It is equipped with a 64bits quad core processor, USB 3.0, dual ethernet, wireless connectivity at the size of 2.5×2.2 inch (56x65mm), making it perfect for IoT and network applications. ROCK Pi E comes in various ram sizes from 512MB to 4GB DDR3, and uses uSD card for OS and storage as well as supporting eMMC module. Optionally, ROCK Pi E supports PoE, additional HAT is required. The SBC that is similar to the ROCK Pi E in the market, is the NanoPi R2S dual Gigabit Ethernet SBC from FriendlyElec, which is powered by Rockchip RK3328 SBC. The major difference between the two SBC is that Rock Pi E is equipped with one Gigabit Ethernet port, a USB 3.0 port, a built-in WiFi, and Bluetooth connectivity which is unavailable on the NanoPi R2S.
The following are specifications of Rock Pi E:
- SoC – Rockchip RK3328 quad-core Arm Cortex-A53 processor @ up to 1.3 GHz
- System Memory – 256MB, 512MB, 1GB, or 2GB DDR3
- Storage – MicroSD card slot up to 128GB, eMMC module support ( 16GB / 32GB / 64GB / 128GB)
