Hello,
Thanks for the advice.
I have published the project (not yet completed) at if anyone wants to have a look at it: mini-elt - EasyEDA open source hardware lab
Another question. Could anyone suggest a 5V to 12V DC-DC booster chip that I can use?
I need to power 2 0.3A per phase steppers and of course my ESP32-CAM. The total should be less than 1.5A@5V (most likely under 1A, but let us be safe!)
