Product description: PCF8591 - ADC + DAC 8bit STEMMA QT/Qwiic I2C - Adafruit 4648
A module containing an analogue-to-digitalADC anda digital-toanalogue DAC with 8-bit inputs. It has an I2C serial interface and is powered from 2.5 Vto 6 V.It has4analogue inputs for voltage measurement and an 8-bit DAC.
Connection and outputs of the module
The module has special leads to which2.54 mm goldpinconnectors(included) should be soldered. Thanks to them itis possible to connect the board to the main module (e.g. Arduino).Below is an example of module connection using STEMMA QT / Qwiic connectorswithMetroboard.
