    Just finished my external trinket m0 dongle using 20mm Coin Cell Breakout w/On-Off Switch (CR2032). Works great! Hoping to add usb c breakout board and maybe some kind of housing.

    Could do but screw on joycon rail stripped don't want to risk it I know there is alternate point for rcm strap but still. I already opened up previously to do battery fix a few weeks back.

    What components do we need? If I follow this guide it'll stay powered on?

    This is by far the best diy dongle project! I’ve bought all your components! Hope I can get a result at least similar to your.

    Ps: can I use directly a microusb to usb C or I must use a microusb to usb a OTG and connect a usb a to usb C?

    Probably one of the simplest/cheapest/easiest dongle solutions so far! Good job. I have around 20 of the cr2032 boards I pulled out of an old display at work. Might give this a crack just so I can use one for something

    Got A trinket but i'm not trying to solder it..Just want A dongle..Will these files work? I want hekate v2.3 on it so when I RCM the switch I just hook this up and press the reset button to run to payload. So I got this right...

    1.Plug into pc
    2.hit reset button twice for bootloader mode
    3.overwrite 3 files on device with the new 3 files i've downloaded.
    4.do what I am looking to do as stated up top.

    Got the micro usb to usb cable and works perfect . Thinking of adding usb c breakout shown in pic. Anyone know alternate solder points as they are tiny. Btw thanks to the Op!

    Is it possible to use a regular Trinket instead of M0?

    It's because the lack of USB Host capability?

    Thank you

    Sure is!

    Clock speed is slower too. And (not 100%) the storage is less too.

    Never owned one but from memory, thats why. People will correct me if im wrong though.

    Got my trinket today. Was planning to do the internal mod.

    Have been having a bit of a mare with the trinket though. I haven't had any luck with even getting it to be detected by my PC to allow me to programme it, or any other computer which I have access to for that matter.

    When the trinket is plugged it, I get the green power light, and nothing else. The RGB LED doesn't blink. Doesn't get recognized as a connected device in Windows. Nothing. I am at the point now where I reckon the board is knackered and I should get a replacement, but was hoping somebody with more experience with this can point me in the right direction for a bit of troubleshooting. I am aware that the trinket has an issue with USB 3.0 ports, so have tried laptops with US 2.0, to no avail. I have tried various USB cables to try and rule that out. I have tried using Ubuntu to see if it will be detected in ubuntu. I have not even been able to get the trinket to show at all on a PC. :( I have ordered another USB sync cable incase this is the issue.

    If somebody might have had any issues with the Trinket M0 before that might be able to offer an insight, I would appreciate it.

    I've spent long enough on this tonight now, so I'm going to bed and will check back here tomorrow.

    Thanks to anybody who is able to offer any advise or pointers. :yay:
