https://www.adafruit.com/product/2000 will be in stock again one day - but with the chip shortage it is hard to know exactly when :/
can you use
https://www.adafruit.com/product/3677
instead? its not exactly the same chip but it is an AVR and 5V/16mhz

Hi! Actually, the itsybitsy was going to be my fallback if I couldn't find any more trinkets! Would it be possible to get those as replacements?
Thank you!
Thank you!

Adafruit, I tried to reflash the bootloader on my sample unit and this is the result I'm getting:
I'm guessing this set of Trinket 5V has failed in an unknown way. Let me know if you want me to hook up the oscilloscope ;-)

you can post a photo of your wiring for the programmer (UNO) and trinket.

Sure!
It is connected as described at https://learn.adafruit.com/introducing- ... bootloader.
Images shared here: https://drive.google.com/drive/folders/ ... sp=sharing
The programming device is an Arduino Nano clone, that's the closest to the Uno I could get. It should operate like an Uno though!
Thanks, Martin.
P.S.: I'm just trying to understand what happened, our customer had his devices replaced (thanks!). This device is out-of-stock at our stores and archived. I have the last device we had in stock to help our customer, I don't expect to need it anytime soon!

Re: New(ish) Trinkets won't flash! Old ones work great!
hmm well i would trace the pins and also make sure the ISP header is not rotated. also of cousre you should see the power LEDs on both boards!

Re: New(ish) Trinkets won't flash! Old ones work great!
I've rewired everything using different wires and avoiding the ISP header. Progress:
I get the same result on repeated attempts! I guess this means that it is mostly working...

Hi,
I used the following guide from Adafruit Introducing Pro Trinket - Re-programming Bootloader with bootloader sketch protrinket5v_bootloader.ino from the downloaded bootloader zipped file.
Let me know if I should try/probe something!
Thanks,
