Want to see if Radxa team may refresh Rock Pi E any time soon, kinda upgrade from RK3328 to RK3566? That would bring a little bit more performance (A53 1.5GHz to A55 1.8GHz), GbE (SoC) + 2.5GbE (1st PCIe lane), USB 3.0 (2nd PCIe lane); maybe a new m.2 B-key slot (USB 3.0) “somewhere” with SIM socket would be very nice for 4G/5G modem for a potential resilient uplink. Given no other brand has m.2 B-key slot in this category AFAIK, I think it can be a good product differentiator.
Currently comparable alternative (if not sold out) would be CM3 (1GB US$30) + E23 ($20), with competitor’s NanoPi R4S 1GB @US$50 and R2S 1GB @US$32, maybe a price at US$40 is doable?
