Introduction
The GR5526 Starter Kit (GR5526 SK) is a development platform based on GR5526 System-on-Chips (SoCs) (supporting Bluetooth 5.3). It contains a GR5526 Starter Kit Board (GR5526 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 a GR5526 SK Board:
By default, display application firmware has been programmed to a GR5526 SK Board. You can view demo graphics by connecting a GR5526 SK Board to a display daughter board. You can also generate firmware by compiling other application example projects provided in a GR5526 Software Development Kit (SDK) and then download the firmware to a GR5526 SK Board for debugging/testing.
Before you get started, it is recommended to refer to the following documents.
