It integrates an STM32G0B1 MCU, TMC2209 stepper driver, ADXL345 accelerometer, and a USB hub, all on a single board. While it retains the same form factor as the original Nitehawk-SB, the v2 features a completely redesigned circuit and layout.\u003c\/p\u003e\n\u003cp\u003eUnlike CAN‑based setups, Nitehawk communicates with the Raspberry Pi over USB, making both software and hardware configuration simpler and more familiar to anyone who has already set up a Klipper printer.\u003c\/p\u003e\n\u003ch3 dir=\"auto\" tabindex=\"-1\"\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSimplified wiring\u003c\/strong\u003e – No complicated breakout cables.

Since there is no longer any breakout PCB, the XY endstop can instead be routed a short distance through the X drag chain and into the toolboard.
