3 phase - It is recommended to measure all 3 voltages with 3 voltage transformers. This can be done by using a main board with 1 add-on board (more information below). A single meter can be used to measure 3-phase, but power (wattage) will not be calculated correctly. Power can be...

Clearly the USB connection is good, power is good, I've tested that 0 and 9 aren't being pulled low by anything, and I've tested with a meter that at least 0 pulls down when I push the button. I'm stumped. One other point: I'm using a Multicore Solders Vaporette vapor phase ...

One difference is that I am now using the 5-volt line on the ESP32 to power the amplifiers. I’m concerned that powering two 3-watt amplifiers with the ESP32 internal regulator may overload it. 5-volts will also give you more output power....
As I said I am not able to get through this phase consistently. If LM317 I am using is not suitable for this circuit and is disturbing code uploading process, wouldn't I wont be able to see the success upload message in the terminal window? From the datasheet I have made a ...
