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, 128×32 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)
