Excellent idea. Thanks for putting this together and sharing. You have solved a real issue that I face on regular basis and had to rely on magnifying glass so far.
Wow et merci beaucoup. Je vois, à travers tes vidéos, que tu es très généreux avec tes infos. Tes explications sur tes sketchs sont apprécié de personnes novices comme moi. 😃
Nice idea ! May I suggest: 1) make similar for ESP32,Wemos D1 mini, Wemos32. 2) Add which signal can be input, or output (mostly for ESP32). 3) make same for the pins down orientation.
Thank you very much for providing this chart and the detailed explanation! This will be very useful. I have a question regarding the VIN pin. You stated that when using the VIN pin, that the USB cable should NOT be connected, as it also supplies power. I don't believe that this is correct. I believe that when there is power being supplied via the VIN pin or the DC jack, the power from the USB is disabled by a mosfet, but the communication pins of the USB are still active. At least this is the case with the UNO, and I believe that this is also the case with the NANO as well. At least I'm hoping that this is the case as I have a large project with 3 NANO's being powered by a regulated 12v power supply (turned down to 10.8v) and I'm updating the NANO's via the USB. Thanks very much. Regards.
