Product description: EMC2101 - I2C fan and temperature controller - STEMMA QT / Qwiic - Adafruit 4808
Module produced byAdafruitand equipped withEMC2101chip. It complies withSMBus 2.0standard and allows to control afanusingPWMpulse width modulator orDAClinear output. It has two built-intemperature monitors- controlling the internal channel and the external channel. Each channel can have aseparately declared temperature range, exceeding which causes an interruption or an alert is sent.
Product compatible with Arduino and Raspberry Pi.
Detaileduser's guideand libraries forArduino IDEandCircuitPythonenvironment are available on manufacturer's website, downloadable from GitHub.
The module is powered by a voltage range of 3 V to 5 V DC.
