Radxa E52C – A Rockchip RK3582 router with dual 2.5GbE, USB 3.0 port, USB serial console port

Radxa E52C is a compact router based on Rockchip RK3582 hexa-core Cortex-A76/A55 SoC and featuring two 2.5GbE ports, a USB 3.0 port, and a USB-C port for serial console access which will make some readers happy…

It’s an update to the earlier Radxa E20C “Mini Network Titan” router, which was limited to two Gigabit Ethernet ports and a USB 2.0 port, and powered by an entry-level Rockchip RK3528A quad-core Cortex-A53 SoC. The Radxa E52C is better in every way with a much faster CPU, higher maximum memory and flash storage capacities, faster networking, and support for USB 3.0 storage or wireless dongles leading the company to call it an “Enhanced Mini Network Titan”.

Rockchip RK3582 router board dual 2.5GbE

On the software side, it’s pretty much the same as for the E20C router with the E52C board running Debian Linux, FLippy OpenWrt, or iStore OS, another fork of OpenWrt with a user interface that aims to simplify the configuration process and also allows the user to easily configure the system as a simple USB NAS. Radxa also provides a hardware access/control library for Linux. But none of that appears to be available right now as the Download section on the product page only contains links to a product brief, schematics (PDF), a components placement map, and 2D drawings at this time.

You can already order the Radxa E52C with 2GB RAM and 16GB flash only on Arace Tech or AliExpress for about $55-$56. Other models are out of stock, but the 4GB/32GB version will go for $65, and the 8GB/64GB variant for $85. Radxa guarantees supplies for the Radxa E52C until at least September 2034. Note that’s the second Rockchip RK3582-based product from the company, as the Radxa ROCK 5C (Lite) was launched a few months ago as a GPU-less Raspberry Pi 4/5 alternative.

That’s exactly what I’ve been looking for over the last year or so. Dual-2.5, native storage, debug port, enclosure. Nothing more is needed. Combine that with a $60 8-port 2.5G switch and you have an easily manageable 9-port firewall. I ordered mine. I’ll see if mainline starts to work on these chips or not :-/

I am wondering if the CPU can support 2.5 Gbit, even worse, 2 x 2.5 Gbit. Obviously switching won’t be hardware accelerated.

it depends what you mean by:

CPU can support 2.5 Gbit

as even the cheaper rk3566/8 can support simple NAT/firewalling at 2.5gbps
but when you add pppoe in the mix (I know you shouldn’t but ISPs have their own agenda) things might become interesting.
Also doing QoS (like SQM) or IPS/IDS at line rate might most likely be too much for this little box
