I wish there was a esp32 board with optically isolated 24v level shifters and screw terminals…

- inamberclad 11mo agoThanks to the open source nature of the Arduino ecosystem, you can make it so!

- general1465 11mo agoYou can search through AliExpress, but I am afraid that your request is so specific that you will need to design something yourself.
- 05 11mo agoThere are optoisolated mosfet modules available on aliexpress, or what exactly do you mean by “level shifters”? What’s your application?
- HeyLaughingBoy 11mo agoThere probably is if you look hard enough. Closest thing I can think of is the MKS-DLC32 motor control boards that are generally used in 3D printers and laser engravers. You can buy just the board and reprogram it. They just run grbl with serial and web interfaces anyway and have an arduino bootloader.
- aaronblohowiak 11mo agoyea, they tend to want to take in tmc2209s or other low-power stepper driver chips.. my use case is to drive bigger (3A+) motors with external stepper drivers. I'd also like to easily use 24v sensors and stuff (hence level shifting and not just mosfets..) something like the teknic clear core but esp32-based.
