The LilyPad Accelerometer is a three-axis accelerometer based on the Analog Devices ADXL335, designed for the LilyPad wearable e-textile system. It detects joint movement, inclination, and vibration, outputting 0–3 V analogue signals on the X, Y, and Z axes.
The board features large sewable pads and a thin 0.8 mm PCB for comfortable integration into clothing and wearable projects. For tilt angle calculation, the analogue voltage needs to be converted to a gravity value using trigonometry; for basic motion sensing, the raw analogue output can be used directly.

Jargon buster
Plain-language definitions for the technical terms used above.
- e-textiles
- Electronic textiles are fabrics or clothing that include electrical parts such as conductive thread, sensors, LEDs, or small controllers. This matters because parts for e-textiles need to survive bending, sewing, and sometimes washing.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- MEMS accelerometer
- A tiny motion sensor made using micro-electromechanical systems technology that measures acceleration and tilt. In a compass module, it helps correct the heading when the board is not perfectly flat.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
