Random firmware resets when turning on your board (forgets settings and you have to rerun detection). Has happened twice to me in 2.5 combined years of unity usage.
Bluetooth module dying/needing replaced. Hasn’t happened to me.
Momentary switch dying. Hasn’t happened to me but I bought extras for when it does happen.
A few antisparks have blown.
Overall seems pretty reliable on the esc scale. Just make sure you check the solder work.
don’t do that. If you will primarily be using it over Bluetooth, set it up from Bluetooth to begin with. ITs when you go back and forth that its most likely to freeze or reset and lose your settings.
if the tiny fuse blows on the battery gauge port you can solder bridge it as long as you never use it for anything other than a battery gauge there’s no real consequence there.
or use an android phone / pad and get it through the play store for Bluetooth. I tried using blutooth from my windows machine once with the app and couldn’t get it to work.
I’ve had mixed results using metr, but there are a lot of people who have used it successfully I believe.
Doing that is usually when the resets happen. But maybe it only usually happens when using the included Enertion BT module and not the Metr unity module. Others may have more experience with this.
I yanked very hard on a wire connection and pulled out both the battery meter wires, causing them to touch while still attached to the unity. They fused together and I had to rip them apart. I tried yelling “fuck” several times but they didn’t separate on command.
