In general, you are correct. But in this case, the board behaves like @mrdude said. The powering of the board is controlled by the enable pin of...
[ATTACH] The idea is to wire to all three buttons. As you have to press power and vol+, these two signals power the trinket on. the vol- button...
I did some small changes in my board and finally ordered it. :-D The new schematic looks like this: [ATTACH] and the board like that: [ATTACH]...
Your cartrige-shaped dongle with included rcm-jig looks impressiv! Really nice done!
Thank you! I'm glad you like design :-) It's not yet ordered, so if you have some ideas for improvements to make it even better, there is still...
Here is my version of a trinket based modchip, with lot of support from @mrdude . Thanks for that! [ATTACH] [ATTACH] [ATTACH] The key...
I think you have marked the power button, not the vol+ button. (The side with the cable is power, IMO). Otherwise it seems good to me, to solder...
@mattytrog thanks for your explanation! Now it makes much more sense! :-) Wouldn’t it be easier to set these signals ([email protected] and [email protected]) at...
@M-O-B I study the arduino sketch you are using to adjust it to my custom board. With your sketch in mind, I doubt that your 5 wire install will...
@mrdude Thanks! Yeah, I tried the circuit on the breadboard, and I will double check it there with the pcb. However, I assumed there, that all...
@mrdude I see, why the bat pin is better! I have here the "assembly" plan and the wiring diagram of chip. Could you double check the wiring...
Hey MrDude The short persists, but I think I have to blame my soldering... Although the pins look okay, it might be, that the pads under the pins...
Nice done! It seems that the second power connection stabilize the supply enough! Good idea! I soldered yesterday another board together, but I...
My custom boards arrived today, yeah! :-) Size comparsion with a trinket: [ATTACH] [ATTACH] Soldering the 48-TQFP was a pain... but after...
@mrdude In case you want to program some sketches on your testboard, you can try my board package file in the Arduino IDE: In Arduino: go to...
The custom pcb has now his own configuration for the Arduino IDE: The board informations are added with the board manager of the Arduino IDE....
Nice to hear that your dev boards have arrived, and will soon have everything together! Also, I'm glad to hear that you will also messing around...
@mrdude Thanks for the bootloader-files. I was able to flash it onto the breadboard chip and it finally showed up as a trinket m0. Double tapping...
@mrdude Thanks for checking the datasheet! As you have mentioned, maybe the actual solution with only one cap works (if high enough). In this...
