PWM Controlled Fan HAT for Raspberry Pi

This feature-packed fan HAT for the Raspberry Pi includes a PWM programmable fan along with a 0.91" OLED screen for displaying your Raspberry Pi's temperature (or anything else you'd like to display!). The HAT also includes a heatsink set, 16 PWM outputs for controlling other PWM devices and handy pin breakouts. The product Wiki includes example code. Features

* 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

* PWM controlled fan, up to 8000rpm speed bringing 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 for even greater cooling

Included

* 1x Fan HAT

* 1x Heatsink set (3 pieces)

* 1x Male pin header

* 1x Standoff pack
