M5Stack HDriver

Using the HDriver and Atom Lite to power a 12v DC Model Railroad controlled wirelessly from an M5Stack DinMeter. Still shaking out the electrical side. Don't know yet if will handle the loads and also that it will survive the odd short circuit -- we'll see...

I like the M5Stack components. They save me from needing to construct circuit boards with all the nuisance that entails. Documentation can be sparse though.
