schematic to connect micro usb to the MCU NRF52840

Hello everyone a basic question but just to be sure.

I would like to make a custom board and I want to program this board with segger Embedded studio, should I just have to wire D- and D+ with D- and D+ of the MCU or should I need to put Something between.

Thank you for your time and have a good Week end ! 

Best regards,

Arnaud

  • What does the nRF52840 Product Specification tell you?

    Look at the nRF52840 Dev Kit schematics for an example ...

  • I checked the NRF52840 dongle as example to make my schematic but what I want to know is it will be possible to direclty code on segger and upload on the nrf52840 because on the dongle, I have to use the NFC programmer.

  • I said the Dev Kit - not the Dongle!

    EDIT

    It's not clear what you mean by "program this board":

    • "program" as in "develop code for"
    • "program" as in "load code onto"

    For loading (aka "burning") the code into the chip, you will need either an SWD debug interface (eg, JLink) or a bootloader.

    With a bootloader, you would still need the debug interface to initially load the bootloader itself.

  • I would like to program it direclty with segger Embedded studio without the help of NFC programmer…

  • It's finnaly Ok ! I didn't understand how everything worked. but now it's ok !
