Discover the Thinnest Flapper ~ just 0.3mm thin! This compact actuator can add eye-catching motion to your projects, transforming them into unique pieces of art. Its easy to attach and comes with a color-changing sticker, to make your creations stand out!

| /



With a flap that's just 0.3mm thin and an actuator at only 2.6mm, this sleek design integrates seamlessly into any flat surface. It's easy to connect with a peelable adhesive back and optional screws, ensuring secure adhesion and flawless installation.

Make Your FlatFlap Smarter & Get started with examples!

Keep things tiny by combine the FlatFlap with our DriveCell and installing our Arduino Library.

The DriveCell Library is available for download on both Github and the Arduino Library manager. Basic functions work on all Arduino boards + optimized PWM functions for CodeCell & other ESP32 devices

  • This flap actuator can reach a speed up to 25Hz, but for always-on applications we recommended not to exceed 10Hz.
  • For smooth organic motions, check out our DriveCell PWM Arduino library.
  • The adhesive used on the backside is 3M467. It’s cover can be peeled off using a pair of tweezers. Always clean the surface before sticking the actuator.
  • The FlatFlap is capable of lifting weights below 2 grams when operated with an on-off approach. Increasing the frequency to resonate the mass, specifically within the range of 30-3Hz, enhances its lifting-force/vibrating speed.
  • The aluminum reflecting flap is not polished and may include some scratches.
  • The box will include the FlatFlap, Blue/Pink Color-Changing Sticker and a set of two M1.2 screws.
  • To mount the Blue/Pink Color-Changing Sticker, peel off its cover-back with tweezers and make sure that the flap's surface is clean.
  • FlatFlap was previously known as the Flap Actuator.
  • This electronics kit is ROHS Compliant & follows IPC-A-600 II standard.
  • Please note that the FlatFlap is intended to be used as a DIY maker kit. For commercial purposes, please get in touch.
