Having a taller matrix connector is really a blessing for those who (like me) have a matrix with a plastic frame that prevents a "normal" connector from being used. It would be nice to also have the option of connecting the driver board to the matrix via a ribbon cable.

One small problem, though: the header pins used for the ESP32 board connection are... strange. They are shorter than normal 2.54mm headers ("normal" for me meaning something like this: https://www.aliexpress.com/item/1005001418544370.html ), and they grip the pins VERY tightly - making connection and disconnection a pain.

as per description, output 680mA measured=within tolerance. PT4115 does the job.

While it's a 2M sensor, this device doesn't have PSRAM, so most you'll be able to capture is 800x600.
But it's still an awesome bit of kit.
