Would UniPi not consider, switching over to ODROID-C2 from RP3 as their central unit?
Or at least consider it as an upgrade option, it's only €10 extra, but the eMMC modules would also cost more than a SD.
The ODROID-C2 is mostly a Korean improved RP3 clone.
I was thinking it myself, but also hear from many people, microSD cards are not really the most reliable storage solution for a PLC type of devices, so a move to eMMC, would not really be a bad one.
- It's 25% faster, always nice, but we properly not need it.
- Gbit networking dedicated true CPU not true USB as on the RP3.
- 2GB RAM
- An extra SD slot for back-up/failover or extra storage, and can be used to upload to eMMC card.
- But above all, it has the much more reliable eMMC5.0 storage option, with a nice speed upgrade.(1).
- Runs standard Linux, instead of Raspbian, so you can use more standard Linux device drivers, like USB RSxxx dongles, and maybe better support for Domotica like software?
- And is pin and mostly hardware, and layout compatible whit the RP3, so it could be implemented whit minimum effort.
- Downside, it's got no BT or WiFi, but that could easily be fixed with €10 USB dongle(2), if people really needed it.
It would be nice to hear what others think of this.
(1) eMMC5.0 is something really desirable from a reliability standpoint, as eMMMC5.0 has a real SSD controller (light version from SATA), mutch better I/O performance, and fewer problems whit write amplification, that could crash your storage over time.
(2) Could also be sold true your website.
