Looks great, have you tried exploring the 3A option?

Thanks! And special thanks to rodocop for all your help on the battery monitor..... sadly it has pretty much been determined that one or both of Tinkerboy's components are causing massive voltage surges and throwing off the scripts.

do you have the tinkerboy dpi in there for the screen?
Unfortunately, yes. Helder and I think it could be the main source of the surging problems. Mine was pulling an awful lot of voltage at times as well. At boot for sure, just like yours was. And also throughout operation. HoolyHoo showed me how to log what the battery monitor script was reading. It was insanely low at times and fluctuated the entire time it was on. Never did get the battery monitor to work. Funny how there is a brand new DPI adapter model on his store now.

Great job there. Looks awesome!

The new DPI Adapter on my website is basically the same with the previous version. I just re-designed it for easier soldering(cooking). Both uses around 160mA which is very little.

If you’re getting a low voltage warning then it’s either two things:
1. Something is consuming too much power more than your power supply can provide.
2. Or the power supply is not providing enough power.
