Review on 🤖 RobotDyn SAMD21 M0-Mini: 32-bit ARM Cortex M0 Core with Arduino M0 Form Mini - Pinhead Soldered & m0 pro Compatible by Douglas Berry

So after trying to get this thing to work for over a week now and trying each of the example Arduino M0 sketches provided in the IDE I never got it, nothing more than an error message "Failed to upload to board." I tried contacting support which in itself was a HUGE feat to even FINDING the support email and they replied ONCE asking what OS I have . I replied within minutes and that was DAYS ago and still no reply. I really hate writing reviews like this because I usually buy from reputable companies like I thought this one was. but due to the lack of support they have promised themselves, I think I may look elsewhere in the future and return my product. The fast blinking blue LED looks cool and the black circuit board is a nice touch. That being said, the device I received is more than just a night light. It still amazes me that there is virtually no documentation on this thing other than the pinout and circuitry. Although there is no data sheet. And no word on if we can get a default bootloader and possibly some instructions on how to boot since it is NOT 100% pin compatible (as they say) with the Arduino mimicking this thing.
