Power Pins

• Vcc - this is the power pin for the NeoPixel LED. It can be powered by any voltage between 3V and 5V. Give it the same voltage as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V; for 3.3V microcontrollers like RP2040, use 3.3V.
• GND - common ground for power and logic.

Potentiometer

In the center of the breakout is the star of the show: the clear shaft potentiometer. It is an RK09K1130D62 10KΩ potentiometer. It has three pins:

• P+ - this is the positive lead pin for the potentiometer
• POT - this is the wiper pin for the potentiometer
• P- - this is the negative lead pin for the potentiometer

NeoPixel Data Pins

• NIn - data input for the NeoPixel
• NOut - data output for the NeoPixel. It can be used to daisy chain multiple NeoPixels together by carrying the data input signal

Power Jumpers

• V+/Vcc - On the back on the board on the left is the V+/Vcc jumper. If you solder this jumper closed, it will connect Vcc to the positive pin (P+) on the potentiometer.
• V-/G - On the back on the board on the right is the V-/G jumper. If you solder this jumper closed, it will connect GND to the negative pin (P-) on the potentiometer.
