I have a Wemos D1 Mini that has no analog outputs, it only has digital outputs at 3.3V.
I need to power a laser with an analog signal 0-5V to engrave pictures on wood. The laser is moved across the image, and needs to adjust the power pixel by pixel. The time spent on each pixel is about 1ms.
The PWM frequency has not been decided yet so I am somewhat flexible with it.
What options do I have to convert this PWM signal to an analog signal? It has to be fast and relatively precise to avoid differences in pixels, so a RC setup is not an option due to strong fulctuations in the signal. (As far as I understood from reading, happy to find out that it is not the case.)
