- MM: I take it tis is the software inside the miner box itself? But how to update it?
- OpenWRT: I take it this is the microSD card inside the Pi? that is I guess easy to update, found some instructions here: https://www.cryptouniverse.at/avalonminer-821-841-861-setup-tutorial-troubleshooting-guide/
- PMU: no idea what this one is!
Thanks
