Here's A Guide To Installing The Trinket M0 Into The Switch.

Program The Trinket Before You Remove The Usb Port, Saves You Doing It After You Complete The Install.

First Thing To Do Is Remove The Usb Port From The Trinket, If You Have A Hot Air Wand Then Use That To Remove The Port It Will Reduce The Risk Of Damage To The Pads.

Now That The Usb Port Has Been Removed You Want To Solder Wire To The Data Pads, White = Data- And Green Data+ In This Guide.

Now Solder Wire To The Bat Pad = Red, Gnd Pad = Black, Pad 4 = Orange & Pad 3 = Brown In This Guide.

Also Remove The Resistor Next To The Ppower Led Mark Out In Purple In This Guide.

When You Have The Trinket All Prepared, You Can Now Proceed To The Install To The Switch.

Once The Install Is Completely Done Then Clean Up The Points You Have Soldered To Using Isopropyl And Cotton Buds/Q-Tips.

Alternative Point For Pad 4.

Alternative Points For Joycon Rail Pin 10.

If You Decide On Using This Alternative Point Then Use Enamel Coated Jumper Wire 0.10mm.

Remember Take Your Time It's Not A Race lol. Rushing Can Lead To Mistakes.

Tools Required.

Kynar Wire 30 AWG.
Soldering Iron.
Hot Air Wand For Usb Port Removal(Optional)
Isopropyl.
Cotton Bud/Q-Tips.
Flux.
Solder.
Enamel Jumper Wire (Optional)

I Think That Covers Everything.

EDIT..

here's another method for the install of the trinket, this method does away with the pad 4, as some may find it tricky to solder to the cap used on the mobo.

the rst pad is used instead and the wire is linked to the power button, Also this has a bonus that you can double press the power button to put the trinket into boot loader mode for uploading a new payload.

of course you don't have to use the rst pad at all, you can't just press power button and volume up button, then press reset button for rcm mode.

this method should be ok for the novices.

install at your own risk.

the pad on the power button to use.

i have one more method to try but I really think this one is not to bad method.

the more methods the better I say, of course to try and make it as easy as possible for pros and novices.

EDIT...
another method for the install of the trinket.

this method is basically same as all other methods, just a different points uses for the bat pad and rst pad.

this install will allow you to have the trinket power off when you fully power off the switch.

double press the reset button on the trinket to get into boot loader mode, this may take a couple of attempts to do.

the payload that you use already will work with this method no need for new ones.

here's the diagram for method 3, you could possibly have this as a 4 wire install, if you install auto rcm mode, but as my sd card module port is buggerd I couldn't test that out.

ok it seems method 3 needs auto rcm installed for it to work without the need to use the rst pad

so for them that don't want to use auto rcm mode then solder a wire from rst pad to the point on the power button, and use pad 3 to the pin 10 on the joycon rail or one of the alt points on mobo.

beware the alt points are small so use at your own risk.

ok anyone with changing issues test these 2 points, you should get 5v on the usb port side, and around 3.2v on the switch side.

if your getting the volts on the switch side that are fluctuating up & down then replace the part with the v on top it's a diode, you want one that fits so the actual size is either 0402 or 0603 in dimension (i'm using 0402/0603 as an example for size purpose only)

around page 16 has more info about this component..

dont come moaning if you damage your console doing this install, i'm not responsible for you opening or taking a soldering iron to your console.
you do this at your own risk any damage is down to yourself.

another thing if your trinket starts to get very hot to the point you can't touch it, then the atmel ATSAMD21E18A-U ic is on it's way out, so you will need to replace the ic or just replace your trinket.

at some point it wont power up after this has happened.
1 = gets very hot.
2 = reset starts to become tempermental .
3 = dead
4 = fix replace the atmel ATSAMD21E18A-U ic

added uf2 drag and drop files for r4 trinket gemma dongles or for a 4 wire internal install.

First Thanks for the Turorial, i solderd a Trinket M0 which i already programmed before i started soldering and tested the trinket m0 with a USB OTG Adapter. i carefully removed the USB port by cutting the Metal Pieces using a drill so i got no demage.
After i soldered the Trinket M0 into my switch it was time to test the ultimate internal Modchip but it won't boot. i booted the switch into Horizon normaly and connect my switch to my pc. i pressed the button twice and my pc detected the trinket without any issues and i'm also able to overwrite the files.

Does anyone have an idea what the problem could be? btw...i booted one time the sx os payload of 50 tries

 

[Crazywhitie]

Installed Trinket and flashed Payload.. Joycons will not work in game when connected to the Switch. but works fine when disconnected... can this be the Payload?

Edit: Controllers work fine in menu when connected just not in Game....

Using SX OS 1.3

never had that issue, can't see it being a payload, have you check tx to see if anyone else has a similar issue. also try a different payload like hekate ctcaer 3.1 and see if it works ok or has same issue.

I think it may be the Right Joycon wire... on the bottom left of the screen it shows the switch but right joycon is not lit up... I'll remove it and test... does same thing on ofw as well... Maybe i'll remove Joycon wire to motherboard..

I'll let you know in case some has same issue.. Thx

That’s the Methode I used to install the modchip but the trinket m0 it still won’t send any payload...i used the newest drag and drop files for sx os from this thread

After I’m in rcm led led turns Purple, orange then red

Are you holding vol up when pressing the power button?

 

[Ferris1000]

yes and my switch turns into RCM how it should be, it lights blue for one second but then Trinket m0 is just lights Purple, blinking orange then the LED turns red for a half second

Did you make sure your microsd card was formatted to fat32 and had the correct files on?

 

[Ferris1000]

my sd card slot is not connected because it should display the Boot.DAT? error screen but it doesn't it stucks in RCM until i send a Payload using my PC or any other device, so it has nothing to do with the SD card because it's not required to send a payload.

 

[mrdude]

If it's not sending the payload, you should check the wires to the usb + and - are soldered properly, maybe you damaged the pads while removing the usb port?

like i already said, if i boot into Horizon without SX OS and connect my Switch via USB to my PC and press the reset button twice it will be detected in Bootloader mode so i don't think it has anything to do with D+ D- GND or BAT connection.

it's not loading the payload it blinks red when it fails to load, should blink green.

check your pad 4 wire ain't touching the cap next to it.

your better off using thinner wire for this install, kynar awg 30 I think is best.

EDIT

remove the pad 4 wire altogether make sure the cap ain't bridged.

then leave the wire off completely, press volume up and power button release then then touch pad 4 with your finger, it should blink green instead off red.

or press the reset button once

i desoldered pad 4 and followed your instruction but now my switch doesn't go into rcm

EDIT:
if i solder pad 4 again the switch turns into RCM when i'm pressing Vol+ and Power but i still get the error message.
I also tried the alternative Point for Pad 4 but it's the same, Trinket m0 won't send the payload. the question is whats about the ID Pin ? the problem with no sending payload began after the Micro USB ID wasn't grounded anymore.

 

[Xandroz]

just want to thank the op for his hard work and by the time my trinket arrives in 10 days hopefully you would have found the best solution to install with less battery drain.

thanks for your hard work

ok then double check the pad 3 to PIN 10 on the joycon rail that maybe the issue for no rcm mode, if you have a big then try that to see if works, remove pad 3 wire point

I'm not to bothered about battery drain, only seems to be 1% difference between having the trinket installed and not installed.

that's with the led still enabled..

Yeah seems it's only like 1.5mA while asleep, which is nothing compared to the sleep mode's drain normally.

 

[M-O-B]

for them that don't want the trinket on when the switch is fully powered off, then use either one of these 2 points on the caps for the trinket bat wire.

these 2 only get volts when the switch is powered on.

Yeah seems it's only like 1.5mA while asleep, which is nothing compared to the sleep mode's drain normally.

without the trinket I went from 83% to 65% in around the same time frame as with the trinket installed.

oh well better see if it's worth buying a replacement ic or not. these things happen

you remove the simple things hoping it's just a blown cap or regulator, but most of the time it's the main part boom.

when you experiment pml.

I'd just buy another trinket. Price difference would be negligible for a single ic

ATSAMD21E18au

around £5 on eBay but microchips direct £2.60 but I'd expect shipping to bump that price up.

so it's most likely cheaper to replace the trinket.
