time to play with the picoverter.
I just ordered 5 boards.
If all goes well I will probably use this to drive the home inverter from now on.

The code will support:
LV cutoff, with timeout and optional restart
Heatsink fan on, off and inverter stop on over temp
Toroid fan on, off and inverter stop on over temp
Optional LCD support, at 9600 baud (actually 10,000 baud. Let's see
what I can get away with)
It needs only one nano. A far simpler control board.
It is compatible with the powerboards we all have, using the 10 pin IDC connector
derived from the PowerJack LF inverters. Best results will be when using
the totem-pole type powerboards.
This is just a prototype.
I plan to design another version of this board to support
much better gate drive design and PCB implimentation
and this will not use the IR2184(4) gate drive ICs.
This second part of the project is still in the design phase
and will need plenty of time yet.
