Next-generation embedded audio
Change how you create with sensors and sound #
The Bela Gem series comprises two boards: Gem Stereo and Gem Multi, both designed to transform the PocketBeagle 2 single-board computer into a powerful platform for real-time audio and sensor processing. Whether you’re an engineer, maker, educator, or researcher, these open-source systems provide the tools needed to create innovative audio projects with minimal setup and configuration.
Key Capabilities #
- Ultra-low latency audio — sub-millisecond performance, 24-bit / 96 kHz.
- Rich sensor & audio I/O — analog, digital, GPIO, I²C/Qwiic, USB host.
- Scalable hardware — Stereo for compact projects, Multi for multi-channel and installation-scale systems.
- Open & accessible — powered by the Bela IDE, examples, and open-source tools.
Two Models – Stereo & Multi #
| Model | Description |
|---|---|
| Gem Stereo | A compact board with high-quality stereo audio I/O and full sensor expansion. Ideal for mobile instruments, prototypes, and small interactive systems. |
| Gem Multi | A larger variant with 10-in/10-out audio (including 8 DC-coupled outputs). Built for spatial audio, research tools, and multi-sensor installations. |

Build expressive systems with audio + sensors #
Bela Gem is designed for projects where timing, precision, and interaction matter. It’s ideal for new musical instruments, responsive installations, gesture-controlled interfaces, effects pedals, wearables, haptics, and embedded research projects. Plug in the USB, open the Bela IDE in your browser, and start building with C++, Pure Data, or the growing library of examples.
The Gem boards provide the same reliable low-latency performance as classic Bela, now with the speed and flexibility of PocketBeagle 2 with a powerful quad-core 64-bit ARM chip and a cleaner, more modular hardware design.
