    EMC2101 I2C PC Fan Controller & Temperature Sensor Module (STEMMA QT / Qwiic Compatible)

    RBD-4157

    This EMC2101-based PC fan controller module makes it easy to control and monitor standard 3-pin or 4-pin PC cooling fans using a simple I2C interface. Instead of handling PWM generation and tachometer counting in your microcontroller, this module takes care of fan speed control, RPM monitoring, and temperature-based automation internally.

    Description

    This EMC2101-based PC fan controller module makes it easy to control and monitor standard 3-pin or 4-pin PC cooling fans using a simple I2C interface. Instead of handling PWM generation and tachometer counting in your microcontroller, this module takes care of fan speed control, RPM monitoring, and temperature-based automation internally.

    The controller supports PWM fan speed control, tachometer feedback, and accurate temperature measurement, making it ideal for cooling electronics, enclosures, DIY servers, 3D printers, embedded systems, and silent/low-noise projects.

    In addition to fan control, the module includes an internal temperature sensor and also supports an external temperature-sensing diode. Using these temperature readings, you can configure automatic fan speed adjustment so the fan speeds up or slows down depending on system temperature—reducing noise and power consumption when full cooling is not required.

    The board is designed in a STEMMA QT / Qwiic form factor, allowing plug-and-play, solder-free I2C connections. Onboard voltage regulation and level shifting ensure compatibility with both 3.3V and 5V systems.

    Key Features

    • I2C-controlled PC fan driver

    • Supports 3-pin and 4-pin PC fans
