- nRF52840의 핵심 핀을 접근할 수 있게 디자인하였으며, USB 인터페이스를 가지고 있어 프로그래밍시에 사용이 가능합니다.
- Raytac MDBT50Q-P1M 모듈을 장착하고 있습니다.
- USB 부트로더가 미리 프로그래밍 되어 있습니다.
- 아두이노, CircuitPython, C를 이용하여 개발할 수 있습니다.
특징
- ARM Cortex-M4 CPU with floating point unit (FPU)
- 1MB internal Flash – For all of your program, SoftDevice, and file-storage needs!
- 256kB internal RAM – For your stack and heap storage.
- Integrated 2.4GHz radio with support for:
- Bluetooth Low Energy (BLE) – With peripheral and/or central BLE device support
- Bluetooth 5 – Mesh Bluetooth!
- ANT – If you want to turn the device into a heart-rate or exercise monitor.
- Nordic's proprietary RF protocol – If you want to communicate, securely, with other Nordic devices.
- Every I/O peripheral you could need
- USB – Turn your nRF52840 into a USB mass-storage device, use a CDC (USB serial) interface, and more. This is a big add compared to the nRF52832!
- UART – Serial interfaces with support for hardware flow-control if desired.
- I2C – Everyone's favorite 2-wire bi-directional bus interface
- SPI – If you prefer the 3+-wire serial interface
- Analog-to-digital converters (ADC) – Eight pins on the nRF52840 Mini Breakout support analog inputs
- PWM – Timer support on any pin means PWM support for driving LEDs or servo motors.
- Real-time clock (RTC) – Keep close track of seconds and milliseconds, also supports timed deep-sleep features.
- Peripheral-multiplexing – (Nearly) any pin can support any of the above features.
