Rock 3A provides faster M.2 storage in the Raspberry Pi form factor

This raspberry pie The form factor is a popular form factor, compact enough to fit some interesting places, but full of power and IO. What the form factor lacks is the possibility of fast and cheap storage.Step forward to Radxa Rock 3A as it was discovered CNX software, It offers a familiar form factor and two M.2 slots for Wi-Fi and SSD.

Following the Raspberry Pi 3B layout, Rock 3A is supported by Rockchip RK3568 SoC, which can squeeze into 2GHz quad-core Arm Cortex A55 CPU, 2,4 or 8GB LPDDR4 RAM. But the most interesting feature of this board is two M.2 slots, one for NVMe SSD (although there are only two PCIe 3.0 channels), and the other with one PCIe 2.0 channel for one of the short “module” cards. For example, a Wi-Fi 6 adapter. The faster M.2 slot is located under the circuit board, but there is no fixing screw, so the M.2 slot is connected by an adapter board, or we need to modify our own solution.
