A Hat to use with the Raspberry Pi as a Secondary MCU in Klipper:
- SKR Pico compatible input for powering the Pi and Serial communication
- 5 Mosfet outputs (with 2 pin JST-XH connectors standard on most fans used on 3D printers)
- Voltage selector jumpers to power each fan from either 5V or VCC supplied by screw terminal
- I2C and 1-Wire and SPI headers for connecting accesories to the Raspberry Pi
- 6 headers connected to General Purpose GPIO pins for accesories such as Filament Run Out Sensors
- On Board DS18B20 Temperature Sensor
