개요

  • 본 제품은 Microchip사의 RN4678 블루투스 4.2 듀얼 모드(BT/BLE) 모듈을 탑재한 제품입니다.
  • 3.3V에서 동작할 수 있게 디자인되었으며, 마이크로컨트롤러와 I2C, UART 인터페이스로 통신합니다.

특징

  • RN4678 module features

    The RN4678 from Microchip is a fully certified, Bluetooth version 4.2 module. Use it to add Bluetooth wireless capability to your project.

    The module includes an on-board Bluetooth stack, power management subsystem, 2.4 GHz transceiver, and RF power amplifier.

    Data transfer is achieved through the Bluetooth link by sending or receiving data through SPP in Bluetooth (BT) Classic mode and through Transparent UART in the BLE mode.

    The RN4678 contains an integral ceramic chip antenna.

    Strong encryption

    The RN4678 module has strong AES128 Encryption. A 128-bit encryption is one of the most powerfull encryption algorithms. AES stands for Advanced Encryption Standard and it is a symmetric encryption algorithm.
