Nitehawk 36:
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 stealthburner 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.
Nitehawk SB V2 is a USB tool head PCB with a STM32G0B1 MCU, TMC2209, Accelerometer all integrated into one board. The form factor is based on HartK’s two piece stealthburner tool head PCB.
What's new with V2:
Onboard microcontroller changed from RP2040 to STM32G0B1
Added USB hub and secondary USB port as in Nitehawk-36
Added general purpose I2C port
Reversed connector gender between main toolboard and fan adapter PCB. The headers are also now keyed prevent misalignment
Probe, TH0, XY Endstop ports changed from JST-XH2.5 to JST-PH2.0
Vastly Improved ESD performance
Features
Convenient wiring, no more complicated and error prone breakout cables - nitehawk only requires 24V power and a USB connector to the RPI host
USB Klipper connection, no additional software or hardware setup compared to CAN
Custom toolhead cable, a single combined USB data and power cable rated for drag chain use, but can also be used in umbilical configuration
Convenient Input Shaping, run input shaper calibration at anytime with an onboard accelerometer
Tacho enabled fans, both hotend and part fan ports are three pin tachometer compatible, allowing for additional diagnostics and safety
Secondary USB port, an onboard USB port allows you to connect a second USB device to your toolhead without running an additional umbilical cable
