Hello everyone,
For my project, I'm making a thermoelectric bracelet for body temperature regulation (essentially a personal air conditioner) and I've been having an issue with printed circuit board. Usually, its pretty easy for me to locate the shorts, but this one is perplexing. As you can see in the schematic, this board is controlled by a Sparkfun Pro Micro. I'll consider that along with the RGBs section 1 of the circuit and that is working just fine.
The problem is section 2 (or so I think) and that's the circuitry responsible for stepping up the voltage and applying the correct polarity (using H-bridges).
When I dont have the boost chip soldered in, power is applied to the microcontroller and section 1 works just fine. However I do notice there is a short between power and ground on the boost converter chip's pads. So its like 1 part of the board is shorted and the other is working just fine.
When the chip is soldered in, both sections ceases to function and my multimeter shows there is continuity between + and - throughout the board.
If someone could shed some light on this problem, I would be very greatful. This one has truly stumped me so if one of you can locate this, then you have earned my highest respect and gratitutde
