I am using a Rak v2

bobcat 300

SenseCAP M1, RAK v1, v2 (Same as MNTD), Bobcat 300, Heltec, Kerlink

If I was to buy one today, SenseCAP M1 and RAK/MNTD because they are still supported, are very reliable and have excellent LoRa concentrator cards. Kerlinks have excellent radios, but are a little slower to report beacons and won’t earn as much in overcrowded locations. The Bobcat 300 and Heltecs have been perfectly reliable for me, but I don’t think there is manufacturer support for them anymore.

I use MNTD myself but listen to @DepinMasterMind

I have only used SenseCAP miners but I have been very satisfied with their performance.

Sensecap is solid for wifi connections, for ethernet connections I prefer Freedomfi

None my man do yourself a service and look at another project haha
