Just so people know there is a version of Windows that runs on the ARM processors and Raspberry pi. Also the inclusion of the rp2040 chip on this SBC I imagine is for some degree of compatibility with hardware designed for the Raspberry pi, while this sbc maybe well priced, I wonder if it could really compete in the performance stakes against the Raspberry pi.
Radxa is offering the X2L, a single-board computer with an Intel processor which is intended as an alternative to the Raspberry Pi and supports Windows. The use of an M.2 SSD is possible.
