PWM Controlled Fan HAT for Raspberry Pi, I2C Bus, PCA9685 Driver, Temperature Monitor

Fan HAT for Raspberry Pi

PWM controlled fan speed via I2C bus, real time temperature monitor

Designed for Raspberry Pi series

Standard Raspberry Pi 40PIN GPIO header, customized for Raspberry Pi series boards

Features at a glance

• PCA9685 PWM driver as the fan controller, powerful driving capability, auto PWM adjustment
• 0.91" OLED, 128x32 pixels, displays board temperature or other user-defined content in real time
• Adopts 3007 size PWM controlled fan, up to 8000rpm speed, brings strong airflow
• Supports retrieving temperature data in real time, and then adjusting the speed automatically, programmable configuration
• I2C pins, for connecting other host control boards
• 16-ch PWM outputs, for driving other external PWM devices
• Comes with heat sinks, better cooling effect
