About the PCB AD5245 Digital Potentiometer

PCB AD5245 Digital Potentiometer is an open source PCB design by CedarGroveStudios, published on GitHub under the MIT license. It is a 2-layer board measuring 17.8 × 15.2 mm, with 10 components from 8 distinct parts.

Other key parts include the AD5245. By type, the board carries 4 resistors, 2 connectors, 2 capacitors, 1 IC and 1 diode.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

A small breakout board and CircuitPython driver for the 10K AD5245 digital potentiometer.

The AD5245 Digital Potentiometer breakout board is a simple implementation of the Analog Devices' I2C, 10K-ohm chip. The potentiometer sports 256 resistance steps and can work with a power source from 2.7v to 5.5v. The pins act similarly to a passive resistive potentiometer, but require that voltages placed on any of the three pins not exceed the power supply voltage or drop below ground potential.
