Meet ECHO: FNDRS EDITION
All-in-one powerhouse.
Available for a limited time only. Act fast.
3DBU will be attending Maker Faire Rochester 2025!
A beginner's dream layout for robotics.
+ Fast and Wireless
Powered by the ESP32-S3, Echo gives you access to one of the most capable chips in embedded tech, ready for WiFi, BLE, and ESP-NOW when your project needs it. From connected devices to responsive robots, the hardware is built to support your wireless ideas.
Don't miss the features.
+ High Versatility
From motor-driven arms to interactive art, Echo adapts to whatever you throw at it. With enough ports to power complex robotics or simple classroom demos, you're never boxed in. One board. Dozens of directions.
+ Convenience
Every pin. Thoughtfully placed. With clearly labeled I/O, configurable sensor power, and a built-in IMU, setup feels natural—even for beginners. No mess, no guesswork, just plug, build, and go.
The Specs
+ Easy To Use
No frustration. No confusion. Just progress. Our open-source library takes care of the complex stuff so you can focus on what really matters: bringing your ideas to life. Whether you're a beginner or a pro, spend more time moving things and less time scratching your head.
