    Dear Lim,
    I’ve received my order with Mini Ultra – it`s cool! thx!
    I`m working on my program for it. I use PlatformIO for the development process.
    And I faced with the issue when I tried to flash program by J-Link via SWD port.

    If right understood, PlatformIO break the bootloader, and one of the board can`t work after it.
    Could you tell me what kind of bootloader do you use for Mini Ultra?
    I really need a good bootloader for low power consumption. With yours one I got 17-21uA in standby mode. And it`s very good result.

    So, if you would be so kind and help me with this issue, it will be great!
    Best regards,
    Dmytro

    Hi Dmytro,
    You can use the Arduino Zero (Native USB) bootloader in the Arduino IDE.

    Bootloader doesn’t dictate the low power but the application code does.

    Hi Lim,

    Thx, it works.
    Do you use Arduino Zero (Native USB) bootloader for the Mini Ultra board too?
    Or yours custom bootloader? If second, what is the difference?
