1. Supports 2230/2242/2280 sizes of solid-state drives (only 2280 copper pillars are welded by default) 2. Only for storage expansion, not for booting from the SSD drive.Only support PClE 1x Gen2. Enable the NVME SSD by add following in the config. dtparam=nvme 3.

Since the ssD speed was limited to 1x Gen2, the current consumption is less than rated, AUX power not needed for most SSD. 4.
