Introduction

Synaptics® Coralboard™ SL 2619 is an edge AI development board built around the Grinn AstraSOM-261x system-on-module, which uses the Synaptics Astra SL2619 SoC with an integrated Coral NPU.

To build a system image for the Coralboard, follow the official Synaptics Astra Yocto Linux Developer Guide and select the sl2619-coralboard machine when setting up the build environment. For initial board setup and image installation, follow the Synaptics Getting Started guide and User Guide.

Grinn add-ons extend the standard functionality of the Coralboard with additional peripherals and interfaces. The Grinn Sense Add-on guide supplements the official Synaptics documentation with add-on setup and testing instructions.
