    Yep, that's the stuff. If you're just intending to just use it once, Amazon sell a brand called BNTECHGO and they sell much smaller lengths for very minimal costs, under £6. I've used it for a long time now, works all the time. Magnet wire is magnet wire.

    What about those two upper and lower capacitors. Which pins are they connecting?
    Beautiful work btw.

    they're connecting VDDCORE and VDDANA to the GND pins next to them, acting as decoupling capacitors for the input and output voltages. this is illustrated in the "build your own from a qfp atsamd21e18" section on the opening post of the thread, and detailed in the datasheet of the chip :)

    To tin this kind of wire, just dip the tip into a glob of molten solder for 3-5 seconds. The heat will burn the enamel off since it's rated for 155C.

    Ordered! Perfect mate, thats exactly what I was hoping for. I made a hard mod for my 3DS that involved soldering 4 wires to the back of a female micro USB that I glued into the case. Best I had for doing this was the thin insulated wire you get in breadboard kits... This stuff should make similar projects a breeze, hopefully...

    Never Mind... I was double tapping the reset button too fast. :blush:

    Can anyone help here please? In my haste I put my trinket m0 into bootloader mode, it appeared as a drive on my PC. I copied over part one dual boot uf2 and the trinket rebooted, came back as a drive again. Then I copied over part 2 Trinket.uf2 then the trinket rebooted and was never again detected at all. it flashes 7 red led flashes and then nothing. Comments and suggestions very welcome!

    [SOLVED] Bad chip, after replacement work like a charm.
    Hi everyone, need help, pls.
    i made trinket m0 analog from ATSAMD21E18A (w/o ldo, led and etc), flash it with trinket bootloader via blackmagic probe, then upload 2 parts of uf2 firmware as discribed.
    intallation in minimal config, 5 wires.
    and here goes trouble.
    with only power button pressed switch boot up normally.
    but in case pwr+vol+ - nothing, black screen. via usb i can see that switch enters in rcm mode, so i can send any payload to it via usb and it will boot in cwf.
    also, i can enter in samd21 flash mode by reset chip twice, send new uf2.
    in fact, everything works but no auto payload injection.
    i'm in dead end. is there something to write on sd, or something to put in switchboot drive?

    sorry for bad english, not native.

    when you flash dual boot you need to press vol+ and pwr to boot up to cfw iirc
    only power starts stock firmware
    or what do you mean with "was never again detected at all" what were your expectations and in which state of SWITCH/Trinket?

    Gave the install a go yesterday.

    First tried with some wire i had laying around from a xbox360 modchip install, wasn't happy with it. was too bulky and the stranded wire was horrible to look at.
    Went and bought some 30awg kynar stuff, wish i had it to start with.
    Vol+ point was very awkward.. Would have helped to use some strong magnification, wouldn't attempt another switch without buying one.
    Went well minus a small slip with the iron trying to get the ground point. Lucky its my own switch.

    Does this modchip also work with Patched Switch models. I have a Team Xecuter SX Pro and this does not work with my patched Switch.. Any infos ?

    Hi,
    I have a little problem with my trinket m0 modchip.
    It is not displayed in Windows Explorer.
    I installed the ModChip in early 2019 and it works as it should.
    But I cannot update the payload.
    The modchip is connected with 4 wires and use autorcm.

    My approach:
    I load the Samd21Update payload and double press the reset button of the modchip.
    But the modchip only shows two red LEDs for the USB initial error.

    I tested 3 different USB C cable's on 3 different PCs.

    Any suggestions on what's going wrong?

    maybe tried to double press slower or faster ? for me it is always a problem of timing to get it shown as drive under windows

    Does a modchip have any effect on the Switch's ability to dock? I installed a 4 wire RCMX86 chip a few months ago. Everything works as it should, the Switch still charges, but when docked it never displays on the TV. The TV light shows on the dock, the Switch display does go off, it charges, there is just not image or sound.
    I appreciate it!

    Nope. No effect.

    I have had problems with dock USB ports functioning after an install. Turned out I had a cold solder joint that was affecting the dock. After re-soldering the chip, it was fixed.

    I suspect you have autoRCM, you need to install the USB strap (brown on the Mattys picture) to make the dock not interfere with the chip upon cold boot
