Built around an ESP32-PICO-D4 System-in-Package (SiP) module, FemtoBeacon has an onboard 9-DoF motion processing unit, a precision altimeter, an RGB LED, one button, two DAC pins, and two GPIO pins. Its small size, light weight, and open hardware design make it an excellent choice for research, AR/VR, and physical computing projects.
FemtoBeacon is a piece of modern computing history. It might very well be the world’s smallest open-source wireless IMU design—and if it’s not, then it’s certainly one of the smallest.
AR/VR applications might transfer sensor data from FemtoBeacon to a more powerful computing environment for analysis within a variety of frameworks, including Unity3D, Node.js, and Processing. Self-balancing robotics implementations will take full advantage of FemtoBeacon’s ability to gather and interpret motion, inertial, and orientation data. Sensor networks and environmental monitoring systems can use FemtoBeacon as a wireless bridge to interface with I²C devices like LED screens and soil-moisture sensors.
And these are just a few of the many projects you might want to build around this tiny device.
