USB Type A Female Breakout Hookup Guide
The board is a simple breakout for USB lines.
GND should be connected to the ground of the host circuit.
D+ and D- are the differential pair lines for USB. They should be connected to D+ and D-, respectively, of the host circuit. Additionally, a 15kΩ pull-down resistor is needed on each D+ and D-.
VCC needs to be connected to a 5V supply (which could come from the host circuit, if available).
