PWM Controlled Fan HAT for Raspberry Pi [Discontinued]

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
