Introduction
The GR5515 Starter Kit (GR5515 SK) is a development platform based on GR551x System-on-Chips (SoCs) (supporting Bluetooth 5.1). It contains a GR5515 Starter Kit Board (GR5515 SK Board), a schematic diagram, and a user guide. The GR5515 SK allows you to get familiar with GR551x-related development tools, quickly develop product prototype, and verify related functions.
By default, no application firmware has been pre-downloaded to a GR5515 SK Board. It is recommended to download the Bluetooth or peripheral example projects provided in a GR551x Software Development Kit (SDK) to a GR5515 SK Board for development and debugging.
To make best use of the GR5515 SK, it is recommended to refer to the following documents.
