There’s small, and then there’s small. The Station M2 is an RK3566 powered board, spotted by CNX Software, is limited in terms of thickness by its Ethernet port, but manages to squeeze a lot of functionality into a case only slightly larger than a credit card.
Inside the Station M2 there’s a Rockchip RK3566 SoC, at the heart of which is a quad-core Cortex-A55 64-bit processor running at up to 1.8GHz. This is the successor to the A53 chip used in the Raspberry Pi 3B+, Nintendo Switch, and some Amazon Fire HD tablets. You also get up to 8GB of LPDDR4, and up to 128GB of eMMC storage. As the name alludes, there’s an M.2 socket for NVMe SSDs, with read and write speeds up to 400MB/s and 392MB/s respectively. The Micro SD slot provides additional low cost storage.
There’s also an HDMI 2.0 port with support for 4k HDR at 60fps, a smattering of USB 2.0 and 3.0 ports including one Type-C OTG that’s also used to power the unit, and a gigabit Ethernet port to complement the onboard Wi-Fi 5 and Bluetooth 5.0. The 3.69 x 2.55 x 0.62 inch (93.8 x 65 x 15.8 mm) aluminum alloy case acts as a heat sink for the RK3566 SoC while keeping the unit neat and tidy.
