I keep having an issue, and it’s clearly me. But I keep melting breadboards. I just realized why, today, as my board next to me started smoking.
I’m going from a 12V battery to a toggle switch to a 12v to 5v converter. From there I go to a terminal block. Half the terminal block is 12V for some downstream things off a relay, and the other half is 5V.
From the 5V half I jumper to + and - lanes of the breadboard. Then I jump from + to VIN and - to GND for the electron.
This is great. I can flip the switch, and power on my particle, power my LCD, etc.
But I flash over USB. So if I’m working remotely, I can be plugged in via USB, switch on the battery off. I can still flash and read serial output.
But I keep melting breadboards if I do this for more than a few hours. So how I can keep plugged in via USB, and not worry about burning down my house while I’m working remotely?
