My computer (and the same cable) works well with Adafruit Metro Mini. I'm using a 2013 Macbook Pro Retina 15' with OS X El Capitan. Do you have any idea what's happening? I believed it's safe to connect the battery adapter to Bluefruit Micro because the battery adapter appeared in the Bluefruit Micro's product page as a recommendation.Īs for the Trinket, my computer never recognized it. After a while, I found that I couldn't see the board in either arduino IDE or system report's USB page. Then I saw a few warnings on my computer saying USB device is drawing too much current, but the Bluefruit's LEDs look as if it's still running, and the LED on the battery adapter indicates it's charging the battery. Then I attached a LiIon Battery Adapter ( ) and a battery to it, to charge the battery via USB.


I was able to use a USB cable to program the Bluefruit Micro at first. I just purchased a Bluefruit LE Micro and a Trinket and many other stuffs. System MacBook (Retina, 12-inch, 2017) MacOS 10.15.7 (Catalina), 12 Pro IDE Version 0.1.2 (0.1.2) Adafruit Trinket M0 I can get the IDE to properly compile my sketch AND transfer correctly to the T.
