Introduction
The GR5331 Starter Kit (SK) is a hardware development platform based on GR533x System-on-Chips (SoCs) (supporting Bluetooth 5.3). It contains a Starter Kit Board (SK Board), design documents, and a user guide. This helps users quickly develop product prototype and verify related functions/performance, shortening product development and go-to-market periods.

Note:
By default, no application firmware has been pre-downloaded to a SK Board. It is recommended to compile the example projects provided in GR533x Software Development Kit (SDK) to generate firmware and then download the firmware to a SK Board for debugging/testing.
Before you get started, it is recommended to refer to the following documents.
