sbc slotIts the first arm sbc i found that could actually be usable as a hh throughput storage node. I plan on using the m key for 2 nvme ssds and the e key for 4 sata hdds. The single lane on the eA Mini-PCIe slot provides expansion options for other cloud connectivity, such as the GW16130 Satellite Iridium Modem, the GW16126 Cat M1 Cellular Modem or other wireless radios.
