Google unveils Coral Board, a compact single-board computer that runs Gemma 3 270M locally without cloud connectivity.

Google announced the Coral Board at Google I/O—a small computer featuring the Coral NPU, an open-source machine learning unit built on the RISC-V architecture. The board contains a Synaptics Astra SL2619 chip with a 2 GHz dual-core processor, 2 GB of RAM, and 1 TOPS of compute.

Google's Gemma 3 270M language model runs entirely on the device. At I/O, Google demonstrated real-time translation, voice-controlled hardware, and a generative music performance where a YOLOv8 model tracked jellyfish movements and turned them into music. All demos are open source on GitHub.

The board is designed for small devices like headphones, AR glasses, and smartwatches to address fragmentation among AI accelerators. It is expected to ship this summer; Google has not announced a price.
