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.
The figure below shows the photo of an SK Board:
By default, no application firmware has been pre-downloaded to an 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 an SK Board for debugging/testing.
Before you get started, it is recommended to refer to the following documents.
