Will MakeCode be able to support the nRF52840 chip or other modules using this particular chip? ---

Thank you @mmoskal. I’ll try them this weekend with the N840 dongle and Feather N840. 🤗 ---

btw, where can I find the working source for the bootloader? I found [https://github.com/microsoft/uf2-nrf5](https://github.com/microsoft/uf2-nrf5) but I was warned: > **Warning** : This project was never fully functional. Please use [https://github.com/adafruit/Adafruit\_nRF52\_Bootloader](https://github.com/adafruit/Adafruit_nRF52_Bootloader) So I tried to follow the recommendation and got this when compiling for **pca10059**. ![uf2-nRF52 for pca1059](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/399daf204340d737177f1f16219d273463d38bbd.png) I also had the same errors with > BOARD=feather\_nrf52840\_express ---

The Adafruit NRF bootloader (which is indeed the one to use) was building for me a few days ago. I suggest you file an issue there. ---

I submitted an issue on Github, [#109](https://github.com/adafruit/Adafruit_nRF52_Bootloader/issues/109) Re-cloning the repo fixed the problem. ---

Update on testing nRF52840 boards: 1.) Feather nRF52840 Express - blinky works. 2.) Circuit Playground Bluefruit - blinky won’t compile. ---

Is there a MakeCode Arcade support for nRF52840 too? ---

Yes, experimental. You need to enable it in About-\>Experiments. You’ll see support for N4 which is NRF52840. You will need a bootloader with your specific pinout for buttons and screen, there’s an example here: [https://github.com/adafruit/Adafruit\_nRF52\_Bootloader/tree/master/src/boards/arcade\_feather\_nrf52840\_express](https://github.com/adafruit/Adafruit_nRF52_Bootloader/tree/master/src/boards/arcade_feather_nrf52840_express) There are no ready-made boards yet though… ---

I have enabled experiments on [arcade.makecode.com](http://arcade.makecode.com) but I don’t see N4 on the list of hardware when downloading the code to a device. ![N4](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/2f96ea3d05eeae41cfadc926a9632746d73ecafd.jpeg) ---

I’m getting this error today with no display on the ILI9341 3.2" LCD. The experiment mode was enabled on [MakeCode Arcade BETA](https://arcade.makecode.com/beta#). ![Falling Duck error](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/55d628a76e4bfd9ca3839923e1859e24f5ecbb11.png) Here’s the [UF2 patch](https://pastebin.com/PHgeewjg) I used. The patch was created using the hex to UF2 Python conversion script found on [Adafruit’s nRF52840 repo](https://github.com/adafruit/Adafruit_nRF52_Bootloader). The display config was modified for the 320x240 ILI9341 LCD. ---

Apologies for reviving this old thread. I’m also trying to get makecode arcade running on a nRF52840 based platform and have the Adafruit .uf2 bootloader on the board. However, when I get the ping game .uf2 and drop it into the board, nothing happens. Is this the correct bootloader? I noticed that Adafruit has arcade based bootloaders for their platforms [https://learn.adafruit.com/makecode-arcade-with-samd51-m4/bootloader](https://learn.adafruit.com/makecode-arcade-with-samd51-m4/bootloader) so would the nRF52840 also need some special bootloader for makecode arcade? When will nRF52840 be offically supported in makecode arcade? I’m using the beta site with experiments enabled. thanks. [Next page](https://forum.makecode.com/t/makecode-for-nrf52840/1164.md?page=2)
