Description
Digital, linear capacitive sensor with analog output or PWM controlled via built-in PIC16F1829 microcontroller that enables the read of 256 positions. The system communicates via the serial interface or the I2C bus. It has the 5V voltage regulator so it works with a voltage of up to 12 V.
Key features
- Voltage regulator of 5 V, which provides power for system with the voltage from 5 V to 12 V
- You can communicate through a simple serial interface and the I2C bus
- Dual digitally controlled resistors 20 kΩ with a resolution of 8-bits
- It has 8 built-in LEDs that can operate in different modes
- The ability to change parameters of the touch sensor
- The ability to configure bus address I2C
- Built-in calibration procedure
- EEPROM memory for data storage
- Four holes for mounting boards with a diameter of 3 mm
- External dimensions of module: 79 x 45 mm

Connection
Board has 15 holes, pitch of 2.54 mm, which allow for soldering the goldpin strap(the set does not have connectors, they can be purchased separately).
| Pin | Description |
|---|---|
| GND | The ground of the system. |
| VIN | Supply voltage from 5 V to 12 V. |
| SDA | The data line of the I2C bus. |
| SCL | The clock line of the I2C bus - it tolerates a voltage of 5 V. |
| RX | Input data line of serial interface. |
| TX | Output data line of the serial interface. |
| PWM | The output of the PWM frequency signal. |
| A1,A2 | Connectors A of the adjustable potentiometer 1 and 2. |
| W1, W2 | "Wiper" connectors of the adjustable potentiometer 1 and 2. |
| B1, B2 | B connectors of the digitally adjustable potentiometer 1 and 2. |
| V+ | A positive voltage of the adjustable resistors, factory connected to 5 V via jumper J1. It should be remembered that the sum of the absolute values of the voltages |V| + |V+| cannot exceed 15 V. |
| V- | The negative voltage of the adjustable resistors, factory connected to 5 V via jumper J2. It should be rememebred that the sum of the absolute values of the voltages |V| + |V+| cannot exceed 15 V. |
