“First venture into ESP32, picked this version as it had the built in battery charger. Having worked with Arduino and Raspberry pi, I coped quite well with this new to me board. Plenty of help on the web for assistance. I should have opted for the version with pre-soldered headers.”
“Great little MCU BUT... there appear to be problems associated withe SDA and SCL pins. Lots of similar reports on line with no solutions. I could NOT get the SDA/SCL to work at all on either of the boards I purchased, which was disappointing given how well everything else works on these boards.”
