Cut and splice one end of a STEMMA QT cable. Then, solder the wires to the PCA9685 inputs:

• STEMMA red wire to VCC
• STEMMA black wire to GND
• STEMMA blue wire to SDA
• STEMMA yellow wire to SCL

This will allow you to plug the PCA9685 into the Feather STEMMA QT port.

Solder the four sets of 4x3 headers to the PCA9685. These headers will be used to plug the servo motors into the PCA9685. You can use a breadboard to secure the headers while you solder.

Solder the included terminal block to the power input on the PCA9685.

Cut off the alligator clips on the DC to alligator clip cable. Then, splice each of those wires. These wires can be inserted into the terminal block to power the PCA9685 with a DC power supply.
