Connection
Pins are the soldered, cornergoldpin connectors with the pitch of 2.54 mm. Thanks to them, possible is the the connection of the board with the main module (e.g. Raspberry Pi orArduino) viawires. The board has additional elements: photoresistor, thermistor, and potentiometer, which are connected to the input pins via jumpers. If the devices are not used, these jumpers must be removed.
| Pin | Description |
|---|---|
| AOUT | The output of the converter D/A. |
| AIN0 | Input 0 of the converter A/D. |
| AIN1 | Input 1 of the sensorA/D. |
| AIN2 | The input 3 of the converterA/D. |
| AIN3 | Input 4 of the converterA/D. |
| SCL | The clock line of the I2C interface, pulled up by the resistor of 10 kΩto VCC. |
| SDA | Data line of I2C interface, pulled up by the resistor of 10 kΩto VCC. |
| GND | The ground of the system. |
| P4 | The jumper that connects the thermistor with input AIN1. |
| P5 | Jumper connecting the photoresistor with input AIN0. |
| P6 | A jumper that connects the potentiometer with the input AIN3. |
