X9C103S Digital Potentiometer Module

X9C103S 10k digital potentiometer module is a variable resistor whose resistance value can be varied digitally from a microcontroller. It consists of a 3-pin output which can replace a mechanical potentiometer which has 3 pins. This module has 99 resistance components and the final resistor is controlled by a 3-wire interface.

Wiring :

• VCC: Module power supply – 5V
• CS: Chip Select. Active LOW
• INC: Changing resistor command
• U/D: UP / Down. Adjusting resistor
• GND: Ground
• VL: Voltage Low
• VW: Voltage Wiper is the voltage output of the adjustable wiper contact
• VH: Voltage High

Features :

• Simple 3 pin interface to control the resistance
• Supply voltage: 3V-5V
• Chip: X9C103S
• PCB board size: 2.7 * 1.3CM
• 10K span potentiometer.
• Potentiometer center tap between 0-10k slide in total 100 (potentiometer wiper typical impedance 40 ohms)
• VL and VH digital potentiometer sliding rheostat port corresponding to the low-end and high-end, allowing the input voltage range -5V to + 5V.
