GR5515 Starter Kit (GR5515 SK) contains the GR5515 SK Board and a schematic diagram.
GR5515 SK Board is a multi-functional development board designed for Goodix GR551x System-on-Chip (SoC) - a Bluetooth Low Energy (BLE) SoC based on Bluetooth 5.1 standards. The GR551x SoC supports Bluetooth Mesh and integrates ARM® Cortex®-M4F CPU internally, with a maximum operating frequency of 64 MHz. In addition, it provides abundant on-chip Flash & RAM and rich peripheral interfaces.
GR5515 SK Board supports full features of Bluetooth 5.1 application development and verification, All Roles, LE Advertising Extensions, 2M PHY, LE Long Range, and Multi-Connection. In addition, GR551x SDK provides rich examples for BLE applications and peripherals, helping users get started on GR5515 SK Board quickly.
GR5515 SK Board offers multiple buttons, LEDs, UART, and a 1.44-inch TFT LCD to help users use and verify the input and output of GR551x SoC. GR5515 SK Board is Arduino UNO compatible, which allows the board to be connected to peripheral sensors, such as G-sensor and heart rate sensor.
The multiplexing of on-board GPIO interfaces facilitates users to extend peripherals such as I2C, I2S, PWM, SPI, and ADC. GR5515 SK Board integrates QSPI Flash to further extend its memory. It also integrates an on-board debugging interface, SEGGER J-Link OB, for program downloading and debugging.
GR551x SDK supports Keil μVision5 IDE and ARM/GCC compiler tool chains.
