Are you looking to buy LDO Nitehawk SB Toolboard V2.0 in Australia?
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.
What Changed From Nitehawk-SB V1.0
- 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.
System Overview
The Nitehawk system consists of three PCBs and the Umbilical Cable. A simplified wiring diagram is shown below:
- Nitehawk-SB v2, this is the main PCB, which houses the MCU, stepper driver, fan drivers, and other circuits.
- Fan Adapter, this is simple PCB receives the part fan, hotend fan, and neopixels and connects them to the main Nitehawk PCB via headers. The main purpose of this seperation is to allow the Stealthburner front to be easily detactable for maintenance.
- Umbilical Cable, this is a custom flex cable that is rated for drag chain use. It delivers 24V power to the main Nitehawk PCB while also carrying USB data.
- USB Adapter, this simple PCB combines 24V power from the power supply and USB data from the Raspberry Pi into a unified connection to the main Nitehawk PCB via the Umbilical cable.
Printed Parts
Nitehawk-SB works with a standard Stealthburner toolhead, and is compatible with both Clockwork 2 and Galileo 2. However there are a few additional custom printed parts. The printed parts are available in the Nitehawk github repo here.
- USB Adapter Mount, this is the mount for the USB adapter PCB. It is designed to be used with a standard Voron DIN clip and can be mounted in two different orientations. It also features a cover to reduce the chance of static discharge onto the PCB.
- Cable Door, this part has been slightly modified from Hartk’s original, with a zip tie anchor added for the external chamber thermistor. The door also accepts a Mx3 Captive screw so it doesn’t get lost easily when you open the door.
- Chain Anchor Tilted, This is tilts the drag chain ever so slightly to help it clear the left XY joint and also avoid rubbing the CT connector on the toolboard.
