Title: OTG power connectors
Post by: zabravanko on May 25, 2016, 07:29:40 pm
Hello guys,
maybe I have a problem with my PIC32-PINGUINO-OTG. It is about its power connectors - there are +5V and +3.3V pins on power con1. I have never used them for supplying aims. Everything with programming the pic32 with pic-kit3 are ok, but when I try to measure the voltage on these pins, I have these results:
- between pins 5V and GND - measured 0V
- between pins 3.3V and GND - measured 2.9V
Actually I am planning to supply a sensor circuit with this 5V pin, but the voltage is missing.. I know how to work and measure with multimeter.
Any suggestions :) ?

Hello again,
I have observed the schematic of the board and .. It was my fault.. When I power up the board thru USB connector, these voltages are ok.
