Description
Single HiLetgo X9C104 digital potentiometer module. It replaces a mechanical trim pot with a digitally controlled resistor you adjust from your Arduino or microcontroller, with no knob to turn and no drift once set.
The X9C104 gives 100 evenly spaced taps across 100K ohms. Pulse the INC pin to step the wiper, set U/D for direction, and use CS to select the chip. The wiper position holds while powered, so it works for bridge balance, offset trim, gain control, and voltage divider jobs that need repeatable settings.
Specs:
- Chip: X9C104, 100 taps, linear
- Total resistance: 100K ohm, range 40 ohm to 100K
- Operating voltage: 5V
- Port voltage: -5V to 5V
- Working current: 3mA
- Pins: VCC, RH, RW, RL, GND, INC, U/D, CS
- Board material: FR4
- Quantity: 1 module
Hookup:
Connect VCC and GND to 5V power. RH and RL are the high and low ends of the resistor, RW is the wiper. Drive INC, U/D, and CS from digital pins. See the pinout photo for the pin layout.
Works with Arduino, ESP32, Raspberry Pi Pico, and any 5V microcontroller with digital outputs. Good for bridge balance circuits, audio gain, sensor calibration, and test fixtures.
