Hello, I am developing a custom board based on the nrf52840 Mini. Is there somewhere I can find that bootloader to flash? I noticed it said it's based off of Adafruits UF2 bootloader but is sparkfuns available for download? Thanks.

Coming back to this, I did specify but I was still intending to use Arduino. I found the Adafruit bootloader source code. Can I flash that UF2 bootloader or would I need to customize it to get my board to appear like the NRF52840 Mini?
