Radxa ROCK 4 SE: New Raspberry Pi alternative arrives with M.2 M key connector
With the ROCK 4 SE, Radxa has created another Raspberry Pi competitor, albeit one without 'Pi' in its name, as is often the case with the company's single-board computers (SBC). According to Radxa, the ROCK 4 SE utilises the Rockchip RK3399-T, a chipset that has two ARM Cortex-A72 CPU cores, two Cortex-A53 CPU cores and a Mali-T860 MP4 GPU. Additionally, the SBC draws on 4 GB of LPDDR4 RAM and eMMC flash storage.
However, Radxa also includes a microSD card reader and an M.2 M key for adding faster SSDs. As marketing images show, the ROCK 4 SE has four USB Type-A ports, two of the USB 2.0 standard and two that operate on the faster USB 3.0 standard. Moreover, the SBC has a Gigabit LAN port, a 40-pin GPIO header, a 3.5 mm audio jack and an HDMI port that outputs in up to 4K at 60 FPS. Meanwhile, Radxa has equipped the ROCK 4 SE with a modem that supports Bluetooth 5.0 Low Energy (BLE) and Wi-Fi 5 connectivity.
Currently, the ROCK 4 SE is orderable from Okdo for £73.34, including VAT. For reference, the SBC costs £61.12 excluding VAT. As it stands, the retailer has stock of ROCK 4 SE units and delivers worldwide. Okdo and Radxa state that the ROCK 4 SE supports Debian and Ubuntu, as well as Android 7.1, Android 9.0, Android 10 and Android 11, thanks to the board's ARM v8 instruction set.
