Radxa Cubie A5E is a tiny single-board PC with an M.2 socket and dual LAN ports for $15 and up
The Radxa Cubie A5E is a tiny but versatile single-board computer that combines an Allwinner A527 octa-core ARM Cortex-A55 processor with up to 4GB of LPDDR4-2400 memory, a microSD card reader and M.2 2230 slot for PCIe Gen 2 x1 NVMe storage, and optional support for eMMC storage.
Available for pre-order from ARACE for $15 and up, the Radxa Cubie A5E measures just 69 x 56mm (2.72″ x 2.2″), yet still manages to feature dual Ethernet ports, two USB ports, and an HDMI port.
The $15 starting price is for a model with 1GB of RAM and no storage, but you can also opt for a 2GB model for $20 or a 4GB version for $30. “Industrial” models with an Allwinner T527 processor will also be available in the future.
Both chips feature eight ARM Cortex-A55 CPU cores arranged in two clusters: the A527 has four cores with top speeds of 2 GHz and four that top out at 1.42 GHz, while the T527’s fastest cores only support speeds up to 1.8 GHz. But the T527 has a few advantages for industrial applications including support for operation at a hotter and colder temperatures, a few extra I/O features, and a 2 TOPS NPU.
Both chips also have a single XuanTie E906 RISC-V CPU core that can run an independent Real Time Operating System (RTOS).
Some of the board’s other features include:
The board supports 5V/4A (20W) USB Type-C power adapters, but one of the Ethernet ports also supports PoE (Power Over Ethernet).
