Nitehawk-36 Rev C+ USB Toolboard PCB with RP2040 Microcontroller, TMC2209 Stepper Driver and ADXL345 Sensor

The Nitehawk-36 Rev C+ is a USB toolboard for compatible 3D printer toolhead systems. It combines an RP2040 microcontroller, TMC2209 stepper driver and ADXL345 accelerometer, with USB communication and 24V power connections for the toolhead.

Key Features

• A USB-based Klipper connection links the toolboard to a suitable host without a CAN setup.
• A secondary USB port supports a compatible nozzle webcam or eddy current probe without another full toolhead umbilical.
• The onboard accelerometer supports input shaper calibration.
• A three-pin, tachometer-compatible hotend fan port supports fan-speed diagnostics.
• The system architecture uses a main toolboard PCB, a USB adapter PCB and a combined USB data and 24V power umbilical. Its cable design supports drag chain or umbilical routing.
