SoC system-on-chip GR551 series

The Goodix GR551x series is a comprehensive-performance single-mode Bluetooth LE 5.1 SoC. It can be configured as a Broadcaster, an Observer, a Central, a Peripheral, and supports the combination of all the above roles, making it an ideal choice for Internet of Things (IoT) and smart wearable devices. Based on ARM® Cortex®-M4F CPU core, the GR551x integrates Bluetooth 5.1 Protocol Stack, a 2.4 GHz RF transceiver, on-chip programmable Flash memory, RAM, and multiple peripherals. The GR551x SDK is the software development kit for the GR551x SoC, offering a complete solution that integrates the protocol stacks, application samples and hardware drivers. The GR5515 Starter Kit is the development kit for the GR551x SoC, and has everything needed for development on a single board. The PLT Lite is the MP tool for the GR551x SoC.
