Mellow FLY-LIS2DW USB Accelerometer Board for Klipper

Mellow FLY-LIS2DW USB Accelerometer Board for Klipper 3D Printers

Upgrade your Klipper-based 3D printer with the Mellow FLY-LIS2DW USB Accelerometer Board — a plug-and-play resonance measurement module designed to automatically tune your printer's input shaper for cleaner, sharper prints. Simply connect via USB to your Raspberry Pi or compatible host, let Klipper measure your printer's resonance frequencies across all axes, and watch ringing and ghosting artifacts disappear from your prints.

Why Choose the FLY-LIS2DW?

• USB Connectivity: No SPI wiring headaches — connects directly via USB for fast, hassle-free setup.
• Klipper Native: Fully supported by Klipper firmware's built-in resonance testing and input shaper calibration workflow.
• LIS2DW Sensor: High-accuracy ST LIS2DW12 accelerometer chip with excellent noise performance and wide dynamic range.
• 5V Powered: Draws clean power from your USB port — no external power supply required.
• No Assembly Required: Board arrives ready to use right out of the box.
• Compatible with Multiple Mounts: Works with V6, MK8, Revo, TZ2.0, and K1 hotend brackets for versatile placement on your toolhead.

Frequently Asked Questions

Q: Does the Mellow FLY-LIS2DW work with all Klipper-based 3D printers?

A: Yes! The FLY-LIS2DW USB Accelerometer Board is compatible with any 3D printer running Klipper firmware. It has been specifically tested and confirmed working with Voron, VzBoT, BLV, FLY-Gemini, and Raspberry Pi setups. As long as your host device has a USB port and runs Klipper, this board will integrate seamlessly.

Q: How does the LIS2DW accelerometer improve 3D print quality?

A: The LIS2DW board measures the resonance (vibration) frequencies of your printer's axes during a short test. Klipper uses this data to configure its Input Shaper feature, which applies a filter that cancels out the ringing effect — the wavy artifacts sometimes visible on print surfaces. The result is noticeably sharper edges and cleaner prints without slowing down your printer.

Q: Do I need to solder or configure any wiring to use this board?

A: No soldering or complex wiring is required. The FLY-LIS2DW connects to your Raspberry Pi or Klipper host simply via a USB cable, making setup quick and straightforward. Just mount the board to your hotend bracket (V6, MK8, Revo, TZ2.0, or K1), plug it in, and follow the Klipper resonance measuring documentation to run your calibration.

Q: Is the FLY-LIS2DW different from an ADXL345-based accelerometer board?

A: Yes. While the ADXL345 is another popular accelerometer used with Klipper, the LIS2DW uses the ST LIS2DW12 chip and connects via USB rather than SPI, making installation faster and avoiding GPIO pin conflicts on your Raspberry Pi. Klipper natively supports both sensors, so the setup process is very similar.
