Bluetooth Low Energy (Bluetooth LE, BLE), also known as Bluetooth low energy technology, is very popular in emerging fields such as healthcare, sports and fitness, beacons, security, and home entertainment. This reference solution is based on the GR5515 Bluetooth low energy SoC, which can help users develop Bluetooth products with central and/or peripheral roles, which are widely used in smart bracelets/watches, electronic shelf labels, trackers, active pens, printers, gamepads and other various AIoT products.
Program Features
This design is based on Goodix GR5515 SoC, which integrates multiple input buttons, LED indicators and UART, supports Bluetooth 5.1 protocol, including all roles, low-power extended broadcast, 2M PHY, low-power long-distance transmission, multi-connection, etc. . Through the multiplexing of GPIO ports, users can easily expand peripherals such as I2C, I2S, PWM, SPI, and ADC.
The development board is equipped with a 1.44-inch TFT LCD display, which is compatible with the Arduino UNO interface, which can be used to connect peripherals, such as G-SENSOR, heart rate monitor and other modules. Key features include:
- Single-mode Bluetooth low energy SoC supporting Bluetooth 5.1
- Multi-function button and LED indicator
- Support Arduino module plug-in interface, IO voltage can be flexibly configured through level shift
- SEGGER J-Link OB supporting debug function
- UART to USB interface
- Micro USB interface to connect to PC
- 1.44-inch TFT color display
- On-board integrated QSPI Flash
