DK9177A
DK-9177A is a BLE 5.3 Bluetooth Low Energy® module based on Nordic nRF52840 MCU (microcontroller unit). The core processor is designed as ARM Cortex M4F, supports high-speed LE PHY 2M, 1M and 125k long-range protocols, and provides flexible design options. It complies with the comprehensive 802.15.4 protocol stack for Bluetooth and Zigbee Mesh protocols. The system development kit supports Nordic nRF5 SDK, NCS SDK and Soft Device and Zephyr projects to help you realize Bluetooth LE applications. GPIO (general purpose input/output) includes: QSPI, SPI, UART, I2C, PWM, ADC, NFC (near field communication, NFC A) and USB 2.0 full-speed interface, which is convenient for connecting with peripheral devices and sensors.
