I can't seem to find the actual schematic for the PCB?

I've been working on a kinda similar thing, designed around a USB<-->UART FT232 instead of a pi, and I'm curious how you're dealing with GPIO0 and 3V3 on the ESP to rest it properly and such things.
I've been planning to use the reset circuit off the D1 mini, but I'm curious as to how you approached it.

This would be useful for programming single or multiple MSP430 units.

Describe the bug
Button won't response if down before state loads

To Reproduce
Steps to reproduce the behavior:

1. Push prog button
2. Start LEMPA (don't let go of the button)
3. Release the button only when it enters the "wait for button" state

Expected behavior
Clicking on a prog button will.. prog but it does not respond
