NiteHawk-36 USB Toolboard PCB by LDO Motors (Rev C+)

All nitehawks ship with revised boards, we have replaced any old batches with new batch parts. Introduction Nitehawk-36 by LDO is a toolboard featuring RP2040 MCU, TMC2209 stepper drive, ADXL345 accelerometer, and USB port. Nitehawk-36's USB-based connection method allows for a simple and easy setup compared to other CAN toolboards. The USB connection also allows for a secondary USB port to connect your nozzle webcam or eddy current probe. If you're looking for the Nitehawk-SB specifically designed for the Stealthburner Toolhead you can find it here. For more information check out the LDO Docs. 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. Secondary USB port, an onboard USB port allows you to connect a second USB device to your toolhead without running an additional umbilical cable. Custom toolhead cable, a single combined USB data and power cable rated for drag chain use, but can also be used in an umbilical configuration. Convenient Input Shaping, run input shaper calibration at any time with an onboard accelerometer. Tacho enabled HEF, the hotend fan port is three-pin tachometer compatible, allowing for additional diagnostics and safety. System Overview The Nitehawk system consists of two PCBs and the Umbilical Cable. A simplified wiring diagram is shown below: Nitehawk-36, this is the main PCB, which houses the MCU, stepper driver, fan drivers, and other circuits. 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.  More information can be found here.
