The Alpon X4 is a mini PC powered by the Raspberry Pi and can connect to cellular 4G LTE networks. This is an edge device, which means that it’s particularly well-suited for professional and industrial settings.

Sixfab is now selling a new computer based on the Raspberry Pi. To be more exact, the Alpon X4 Edge is based on the Raspberry Pi Compute Module 4. Essentially, the manufacturer Sixfab packs the Compute Module 4 onto a specific motherboard and offers the usual ports in a practical case.

The four external antennas for wireless connectivity are clearly visible, which could contribute to good reception and fast data speeds. The mini PC supports both the usual 2.4GHz and 5GHz WiFi bands, as well as Bluetooth and even 4G LTE.

Without the aforementioned antennas, the computer measures about 4.4 x 3.9 x 1.3 inches. The Alpon X4 Edge can be mounted on a DIN rail, which is common in industrial settings where the Sixfab mini PC could be used to control or monitor certain machinery.

With a corresponding add-on board, further devices can be connected via GPIO. That said, the default configuration also sports two USB 2.0 ports, Gigabit Ethernet and another slower Ethernet port with 100 Mbit/s. External displays are supported.

Furthermore, the mini PC can be powered via USB Type-C or regular power cables with 9 to 30 volts. Last but not least, the 4G-capable Sixfab Alpon X4 Edge has 8GB LPDDR5 memory and 32GB eMMC mass storage for an official list price of €550.
