3117 breakout is an open source PCB design by r4hulrr, published on GitHub under the MIT license. It is a 2-layer board measuring 22 × 20 mm, with 14 components from 13 distinct parts.
Other key parts include the TLV77018PDBVR and MAX30102. By type, the board carries 6 capacitors, 3 resistors, 2 ICs, 2 diodes and 1 connector.
It belongs with the sensors, iot & wireless and audio designs in this gallery.
From the project
Real-time Auslan (Australian Sign Language) to English speech translation glove. Built with ESP32-S3, flex sensors, IMU on a custom PCB, and a Bluetooth-connected Python GUI.
Breaking communication barriers for the Australian Deaf community with an affordable, wearable, real-time Auslan-to-speech translation glove. Check out the demo video.
Unlike existing ASL-centric devices, AUSIGN is purpose-built for Auslan, incorporating contextual awareness via a heart-rate sensor, low-latency audio feedback, and Bluetooth connectivity for flexible output through a mobile/desktop app.
