Radxa E25 is a modular router with two 2.5GbE ports based on the Radxa CM3 Industrial (CM3I) system-on-module equipped with a Rockchip RK3568 quad-core Cortex-A55 processor, and optional support for WiFi 6 and 4G or 5G cellular connectivity.
I got an early sample of the Radxa E25 carrier board in January, but the company has now refined the design with version 1.4 of the board and will launch the Radxa E25 as a complete router with an enclosure similar to NanoPi R5S and LinkStar H68K we’ve covered previously.
Radxa E25 specifications:
- SoM – Radxa CM3I with Rockchip RK3568 quad-core Cortex-A55 processor @ 2.0 GHz with Arm Mali-G52, up to 8GB RAM, up to 128GB eMMC flash (250MB/s max), optional WiFi and Bluetooth
- Storage – MicroSD card socket, M.2 SATA 2242 SSD (multiplexed with 4G)
- Networking
- 2x 2.5GbE ports via Realtek RTL8125B 2.5 Gbps Ethernet transceiver (Tested by Radxa at 2.2 to 2.3Gbps)
- Optional support for WiFi & Bluetooth via mini PCIe socket (multiplexed with 5G)
- Optional support for 4G LTE via M.2 socket, 4G or 5G via mini PCIe socket; SIM card slot
- USB – 1x USB 3.0 OTG port up to 5Gbps, 1x USB Type-C port
- Expansion
- mini PCIe socket with SDIO, PCIe Gen 2.0 x1
- M.2 Key B socket with SATA
- 26-pin expansion header with up to 17x GPIO, 3x UART, 2x SPI, CAN Bus, I2C, I2S, ADC, 6x PWM, 5V, 3.3V, and GND
- Debugging – Serial console via USB-C port
- Misc – User button, 16x RGB LEDs
- Power Supply
- 5V via USB-C port (2A recommend without peripherals, 4A with multiple peripherals)
- 5V via GPIO 2 and 4
- Dimensions – PCB: Approx 75 x 70 mm
The M.2 socket has been tested with Lenovo M.2 2242 SATA SSD and Quectel EM05 4G LTE module, while the mini PCIe socket has been confirmed to work with DR900VX WiFi access point module, Quectel EC25 4G LTE module, and Quectel RG200 5G module. Radxa will provide Debian and Ubuntu server images, as well as a hardware access/control library for Linux that you eventually become available in the wiki.
Radxa could not give us availability information, but they did provide pricing for three variants of the router with case and heatsink:
- $59 for 2GB RAM and 8GB eMMC flash
- $75 for 4GB RAM and 16GB eMMC flash
- $109 for 8GB RAM and 32GB eMMC flash
The Radxa E25 modular 2.5GbE router will be sold on Allnet and Ameridroid, but we just don’t know when just yet although we were told long term supply will be guaranteed until September 2029. [Update: the router is already available on Allnet China]
