PCF8591 AD-DA Converter Module with Built-in Sensors

This module has 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. Now you can connect your own sensor via a DuPont cable.

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