AdafruitPro Trinket 5V 16MHz (1 Piece)

I liked the fact that it was easy to program, but not so happy that I had to buy a cable to program it!

Mon pc n'arrive pas à le detecter

Nutze ihn in einer Wetterstation für die Astronomie, Stromaufnahme ist vernachlässigbar, reichlich Flashspeicher für einen Mikrocontroller, passt.

The Pro Trinket is an a great piece of hardware. The sketch I designed on my Arduino Uno loaded right into the trinket and worked as it should. The size is very small, can fit into very small projects. The only think I had to do to load the sketch was press the button on the board first, then it would take the sketch. I read this on a forum somewhere when I was having problems loading it. Great board, will be getting another soon for another project.

I have successfully used the Adafruit Trinket Pro for a bunch of projects and bought 2 new ones for a new project. For this project, I used 2 that I had bought directly from Adafuit and these 2 new ones. The new ones simply flashed the error light at me and would not accept the download program (the same one I loaded successfully to the 2 old ones so the issue is not with my cable, computer, program setup, etc...). I tried the instructions for re-burning the USB Loader, which is one possible cause of the lights I had, but even that did not work. Additional forum search seems to indicate the units are broken so I am returning both. I had to scramble at the last minute and substitute 2 full-size Arduino Uno's I had lying around. I have to wonder if this seller is passing off reject units as "new". I will stick to buying directly from Adafruit in the future. I am giving 5 stars but those are for the Adafruit unit - I'd like to give 0 for this seller (in my case, shows as "3DMakerWorld")!
