Ophelia-I EV NRF52805

Overview

The we_ophelia1ev_nrf52805 board is an evaluation board of the Ophelia-I radio module. It provides support for the Nordic Semiconductor nRF52805 ARM CPU and the following devices:

  • CLOCK

  • FLASH

  • GPIO

  • I2C

  • NVIC

  • RADIO (Bluetooth Low Energy)

  • RTC

  • Segger RTT (RTT Console)

  • SPI

  • UART

  • WDT

Hardware

The Ophelia-I uses the internal low frequency RC oscillator and provides the so called smart antenna connection, that allows to choose between the module’s integrated PCB antenna and an external antenna that can be connected to the available SMA connector.

Programming and Debugging

The we_ophelia1ev board supports the runners and associated west commands listed below.

flash debug

Flashing

Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing. Then build and flash applications as usual (see Building an Application and Run an Application for more details).

Here is an example for the Hello World application.

First, run your favorite terminal program to listen for output.

$ minicom -D <tty_device> -b 115200

Replace <tty_device> with the port where the board nRF52 DK can be found. For example, under Linux, /dev/ttyACM0.

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b we_ophelia1ev/nrf52805 samples/hello_world
west flash

Debugging
