Nevermore StealthMax PCB by xbst_isik

An open source, STM32G0B1 based controller for the Nevermore StealthMax air filters for 3D printers. The PCB eliminates the complicated wiring needed for the Nevermore StealthMax, it adds 4-pin PWM fan control for the filter fan, reads sensor data from I2C air quality sensors (see Nevermore Sensor PCB) and controls LEDs. The board works with Klipper firmware and communicates via CAN Bus or USB Micro to the connected controller board.

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.
