Nevermore StealthMax PCB 2

The Nevermore StealthMax PCB 2 is an open source, STM32G0B1 based controller for Nevermore Stealthmax air filters for Voron 3D printers. It 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.

Features:

• 1x 12V 4-Pin PWM Fan Connector
• 2x 3.3V I2C Sensor Connectors
• 1x 12V UV LED Connector, MOSFET Dimming
• 1x 12V AUX UV LED Connector, PWM Signal
• 1x 24V Peltier Connector, MOSFET Control
• 1x Thermistor Connector
• 1x 3950 Thermistor on PCB
• 24V Power Input, 12V & 5V Buck Converters
• CAN Bus or USB C for Communication with Klipper
• The JST-PH, MX3.0 and XT30(2+2) connectors and pins for the connectors on the PCB are included.
