An open source, STM32G0B1 based controller for Nevermore Stealthmax air filters for Voron 3D printers. Eliminates the complicated wiring needed for the Nevermore Stealthmax, adds 4-pin PWM fan control for the filter fan, converts 24V power to 12V, 5V and 3.3V power, eliminating needing separate buck converters or more complicated wiring, reads sensor data from I2C air quality sensors, controls UV LEDs and peltiers and reads thermistors. Works with Klipper firmware. Communicates with Klipper via CAN Bus or USB C.
