Nitehawk-SB V2.0 Toolboard

Introduction

Nitehawk-SB v2 by LDO is a toolboard specifically designed for the Voron Stealthburner toolhead. It is a toolhead PCB featuring STM32G0B1 MCU, TMC2209 stepper drive, ADXL345 accelerometer, USB HUB all integrated into one board. Nitehawk v2 retains the same form factor of the original Nitehawk-SB but much of the circuitry and layout has been completely redesigned from the ground up. 

Nitehawk uses USB communication with the RPI rather than CAN. So the software and hardware setup is far simpler and familiar to most people who have setup Klipper printers before.

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.

Changes from the Nitehawk-SB v1

• 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.
