Blinky Example


Blinky Example is a simple application which blinks an LED forever using the digitalio module. The source code shows how to configure the GPIO pin as output, then turn it on and off.

The table below shows the available LEDs on the nRF52840 M.2 Developer Kit:

Available LEDs Mounted on Pin Name
Red LED M.2 Module P0_30 LED_RED
Green LED M.2 Module P0_29 LED_GREEN
Blue LED M.2 Module P0_31 LED_BLUE
Green LED M.2 Dock P1_07 D13

Before you start coding, the Python Interpreter should be installed on the nRF52840 M.2 module correctly:

Run the code

Run the Blinky Example by performing the following steps:

  1. Connect the Module USB port to your PC as shown in the figure below. A disk drive called CIRCUITPY should be automatically detected by the computer:

  2. Open the file on your CIRCUITPY drive, then copy and paste the following code:

    import digitalio
    import board
    import time
    led = digitalio.DigitalInOut(board.D13)
    led.direction = digitalio.Direction.OUTPUT
    while True:
        led.value = True
        led.value = False
  3. Your code will run as soon as the file is done saving. Observe that the LED starts to blink:
