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
