NiteHawk 36 USB toolhead (revised version ) by LDO

Introduction

Nitehawk-36 by LDO is a tool board 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.

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.
