The QN9080DK board is designed to make it as easy as possible to get started with your project based on the QN908x Bluetooth Low Energy MCU. The QN9080DK board integrates buttons, Piezo buzzer, and LED for an easy way to reset chip and indicate chip status. The DK board also provides useful interfaces such as USB port for UART communication and CMSIS debug. The board contains the QN9080xHN chip, CMSIS-DAP offering software development and UART interfaces for QN908x debug and communication, Mini USB port for power and a communication port, and an Arduino interface to ease system prototyping.
