Nevermore StealthMax & Mini PCB

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 "real" (AKA 4-pin PWM) fan control for the filter fan, reads sensor data from I2C air quality sensors and controls LEDs. Works with Klipper firmware. Communicates with Klipper via CAN Bus or USB Micro B.

Features:
- 1x 4-Pin PWM Fan Control
- 2x I2C Sensor Connectors
- 1x LED Connector
- 1x CAN Bus Connector

The JST-PH connectors and pins for the connectors on the PCB are included.
