Product description
Controller board for PC fans with inputs for tachometer and temperature sensor. An onboard temperature sensor complements the external one, with ±1 °C accuracy. Controls fan speed via a programmable PWM output.
Controlled via I2C.
Based on the EMC2101 chip.
Cool your projects, reduce noise from constantly full-speed fans, and more. Advanced features include table-based temperature-to-RPM control, programmable ramp-up and ramp-down behavior, minimum speed setting, PWM frequency adjustment, and support for 6-bit analog voltage output (DAC mode instead of PWM) for maximum flexibility.
Supports both 3.3 V and 5 V. Compatible with SparkFun Qwiic and Adafruit STEMMA QT.
