Build a shutter tester for Focal Plane shutters - Cheap, Easy & it Works

I really do appreciate all your help. I moved hastily because I found one that came with the expansion board - so I know it fits correctly.

I was worried because the linked board seems to be the “32D” variety while mine is ESP32”S”. Research lead me to believe it’s an older version. As long as I don’t fry anything - I’ll be happy

I had loaded the bin file etc before the other parts arrived. Traveling for a week - so I’ll get the rotary switch and anything else needed to test/generate code wired up when I return.

Thank You!

I'll send some thanks as well. The parts have left China and with some luck should be here next week for me to make an update on the (non screen) build and flash. I'm sure that I will be back with some questions quite soon! Thanks again!
