The Quick2Wire PCF8591 I2C Analogue Board has four 8-bit Analogue Inputs and one 8-bit Analogue Output.
You can use the boards to measure four voltages and control one output voltage. A simple Python API allows you to control the on-board PCF8591 chip and access all of its features.
The board uses our I2C bus connectors. It is intended for use with our Interface Board. The product is supplied in kit form, so you will need to assemble it yourself. The basic kit includes a connector cable but not a Raspberry Pi or an Interface board.
