I am looking at a 5 pin connector on a device. I know which pin is #1 (square pad on circuit board).
Typically USB has 4 wires. (this is just a google of USB wiring standards).
1 - VCC - 5VDC
2 - D - - Data - White
3 - D + - Data + Green
4 - GND - Ground
5 - Unknown
5 Pin connector is tiny such that I should go inside and just solder wires to the circuit board.
Using a VOM I shouldn't have an issue with VCC and Ground.
I don't think I will mess anything up switching the data lines.
Just curious if there is an easy way to check the IN/OUT data lines.
Guessing that pin #5 could be some sort of switch to enable or disable the USB port? Major guess though.
Here is a picture of the circuit board and pinouts.
Just forgot that I can power the board with nothing plugged into it. Plugged in board and see via VOM
1 - VCC - 5VDC
2 - D - White
3 - D-+Green
4 - ID N/A Permits detection of which end of a cable is plugged in:
• "A" connector (host): connected to the signal ground
• "B" connector (device): not connected
5 - Ground
Pins 2 & 3 are the Data lines.
I have a little USB breakout box. Tested the above to work fine.
