AD/DA converter module PCF8591

This module features 4 analog-to-digital (A/D) converters, 1 digital-to-analog (D/A) converter and 3 built-in sensors: a light sensor, a temperature sensor and a potentiometer. The sensors are connected via the included 2P jumpers. If a built-in sensor is not used, the jumper can be removed. This allows you to connect your own sensor via a DuPont cable.

The module is connected to a microcontroller via an I2C interface.
