LDO Nitehawk-SB v2.0 USB Toolboard

The LDO Nitehawk-SB v2.0 is a USB-based toolboard designed specifically for the Voron Stealthburner. It combines the MCU, stepper driver, accelerometer, fan control and USB hub on the toolhead, requiring only 24V and USB to connect to Klipper instead of a CAN setup.

V2.0 improvements

• STM32G0B1 MCU, TMC2209 stepper driver and ADXL345 accelerometer
• Integrated USB hub with a secondary USB port
• Tachometer signal support for both hotend and part-cooling fans
• Improved ESD protection and keyed connectors on the fan adapter
• I²C, probe, temperature input and X/Y endstops
• JST-PH 2.0mm connectors for probe, TH0 and X/Y endstops

Compatibility

Designed for the standard Voron Stealthburner and compatible with Clockwork 2 and Galileo 2. Additional printed parts from the project's GitHub repository are required and are not included. The Nitehawk-SB v1 cable and USB adapter can be reused, but the v1 fan adapter is not compatible with v2.
