AD/DA converter module PCF8591 (OT8823)

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 in use, the jumper can be removed, allowing you to connect your own sensor via a DuPont cable.

The module connects to a microcontroller via an I2C interface.
