Nitehawk is a toolhead PCB with a RP2040 MCU, TMC2209, Accelerometer all integrated into one board. The form factor is based on HartK’s two-piece stealth burner toolhead PCB but with some minor changes
Features
Greatly simplified wiring, a single wire runs through the drag chain or in an umbilical setup. No additional breakout cables needed.
Based on Klipper USB, no additional hardware or software setup compared to CAN.
Tachometer enabled fan ports (PCF and HEF), allowing for fan speed detection.
Integrated accelerometer for convenient input-shaping.
The online documentation is a little weak for a noob like me. I was able to work it all out. Hardware is good so far. Don't know about the life expectancy.
