Adafruit EMC2101 I2C PC Fan Controller and Temperature Sensor - STEMMA QT / Qwiic Camera Case check out the NeoPXL8 ArduinoCooling fans are essential for keeping electronics cool, but controlling fan speed can be complex. The Adafruit EMC2101 from Microchip SMSC simplifies this with a fan controller and temperature sensor that supports 3 or 4 pin PC fans. This breakout board features programmable PWM output, tachometer input for monitoring fan speed, and both internal and external temperature sensing with 16C accuracy. Key capabilities include: Control fan speed with PWM
