Internal modchip - SAMD21 (Trinket M0, Gemma M0, ItsyBitsy M0 Express) Guide, Files & Support

Notice: I am not receiving notifications for this thread. I didn`t realise people were still posting in it.

Please please accept my apologies if I haven`t replied to tags etc... I have no idea what is happening. I`m subscribed to this thread but I am not receiving notifications. Please inbox me if possible. Or tag me in another thread.

Its amazing that people are still checking all of this out. I thank you for all of the help and support I have received in this thread over this year.

Cheers. Matty.


A video showing a modchip in action. Thank you once again to @metaljay for providing this. This is what you can achieve by fitting a chip!



Section 1. Gather your software.

Get your chip software from THIS THREAD.
Follow the flashing instructions there...




Section 2. Removing USB port and unneeded LEDs. (Adafruit chips only)
  • Next, we need to remove the USB port from the modchip. I recommend a heatgun or a rework station. Heat up until the USB port just lifts off the modchip.
  • Do the same for the LED just to the right of the USB port.
See picture:

You are now ready to fit your device. Proceed to Fitting section.





Section 3. Fitting modchip to your Switch.
New Universal Method. All SAMD-based internal chips. If your chip is not supported and you cannot work it out, PM me.

BUILD YOUR OWN FROM A QFP ATSAMD21E18. Trinket equivalent pins.
Flash Trinket bootloader using OpenOCD via serial pins SWDIO / SWDCLK. Fit a reset switch somewhere... Or going to power / wake (aka method 2). If building for external use, it is good practice to fit a third capacitor between 3V & GND. This is deliberately vague and ambigious, as this needs research and you need to know what you are doing.

Replacement Parts List

Ok... So you have damaged your switch soldering your chip in. Not to worry.

First things first, DO NOT BRIDGE THE CONTACTS HOPING TO REVIVE YOUR SWITCH. With resistors, you may possibly get away with this, but with the capacitors listed below, if you jump these points, you will make a nice short-circuit to the PMIC and / or the M92T36, killing them instantly. Don`t do it.

OK... I`ll list these parts with METHOD 2 & 3 TRINKET PIN NUMBERS and the values of the components they solder to.

TRINKET 3V (POWER SUPPLY) - 2.2uF 0402 size MLCC capacitor. Voltage unimportant as long as it is over 6.3v
TRINKET PIN 2 (POWER ON RESET - goes to pin 5 on M92T36)- 4.7uF 0402 size MLCC capacitor. Voltage unimportant as long as it is over 6.3v
TRINKET PIN 0 (VOL+) - 150R (150 ohms) 0201 Thick Film resistor. 50mW
TRINKET RESET (SWITCH POWER BUTTON) - 150R (150 ohms) 0201 Thick Film resistor. 50mW


I recommend RS components.

FAQ

Q - How do I boot the switch into APX (RCM) mode?

A - You need to short out pin 10 on the right joycon rail to GND with a jig or modded joycon or paperclip (not recommended... Buy a jig you cheap-ass gyppo). Once shorted out, hold down vol+ and power. The switch screen should be off... Plug into your PC and it should recognise a APX device. Well done. You are in RCM.

Q - What glue should I use?
A - Only glue if necessary! Ideally if your soldering is of sufficient quality and your wire is thin enough, you don`t need glue. I use a bit because I am OCD. Anyway, use Epoxy. It`s what I use. Gives you some working time, is solid. Superglue makes a mess DO NOT USE SUPERGLUE. The only thing super about it is how it melts things. Epoxy won`t stick to the shield long-term, so bear that in mind. Pure Acetone will remove epoxy. Acetone tends to remove / melt anything to be warned. CHECK YOUR GLUE WON`T GO CONDUCTIVE OVER TIME - LOOKING AT YOU SCAMSUNG! The combination of heat cycles and absorbing of moisture can turn adhesive into a high-impedance connection!

Q - What size wire should I use?
A - I use AWG40 magnet wire or AWG30 Kynar. AWG40 goes onto components easier... And if you snap it, chances are the wire will snap and not the trace / component.
A2 - You can also use AWG30. I recommend Kynar wrapping wire but any will do. Looks nice, good resistance to elements, tidy. Nothing thicker than AWG30. You are just causing yourself more headaches. Trust me.

Q - Is AWG40 thick enough?
A - Yes. AWG40 is good for around 90mA.

Q - which methods do you recommend?
A - Connect all the straps...

Q - how do you recommend to set it up?
A - Fusee Suite. Search for Fusee Suite or go to link at top of this OP.

Q - My switch is flat and won't turn on.
A - Have you got the charger connected? Disconnect it or your switch won't boot! Boot to a payload (SX loader/Hekate), reconnect charger and leave on the payload menu and charge. Leave for 15 minutes and switch will start normally. It will continue charging one booted.

Disclaimer:
You have only yourself to blame. This voids warranty. This may or may not get you banned from online services. If it does, you got yourself banned. I`m not responsible if you kill your switch / your first-born with any of this in this post. I`m not infalliable. I`m partly senile. Do your own research. Kids, get bill payers permission before you attempt even using a screwdriver.
NUTSHELL: Don`t come having a go at me because you fooked your £300 console up. I`ll do my best to help you though if you do, Just don`t blame me.

IF YOU REQUIRE SUPPORT, IF YOUR CONSOLE ISN`T WORKING CORRECTLY... PLEASE POST A HIGH RESOLUTION PICTURE OF YOUR INSTALL. You might think it isn`t your soldering, but in all cases with the new methods, it is bad soldering. So, please post a picture.


A BRIEF WARNING - PLEASE READ
THIS MOD IS NOT FOR THE FEINT OF HEART. WE ARE SOLDERING TO TRACES AND COMPONENTS ON THE FRONT SIDE OF THE BOARD TO SAVE HAVING TO REMOVE THE BOARD AND SOLDER TO TESTPOINTS. IF YOU ARE STRUGGLING, OR THINK YOU ARE GOING TO STRUGGLE, PLEASE PLEASE SOLDER TO THE TEST POINTS NOTED IN THIS AND OTHER THREADS (YOU WILL NEED TO REMOVE THE MOTHERBOARD). DOUBLE - TRIPLE CHECK EVERYTHING. YOU HAVE BEEN WARNED!!!
Good soldering skills are needed!
A magnifying glass is needed!
Good soldering iron needed - ideally with a 0.3 conical tip. No more than 30w!
SECURE YOUR WIRES PRIOR TO SOLDERING. Stick them down with double-sided tape.
Only use glue if you need to and glue wires after soldering. Don`t glue the solder to the component!
Put the tiniest amount of glue on the PCB mask only. Never on components. Use a cocktail stick for more glue control!!!
Take a look at alternative solder points to get you out of the sh*t if you do rip something off the board
If you aren`t the best at soldering, then think very carefully about connecting to pin 6 capacitor (the one in these new methods). If you rip this pad, you WILL NEED TO REMOVE YOUR BOARD and run from a testpoint.

Does anyone have one of them RCM_X86 things?

If so, can someone try this out?

Its a version of my multipayload. "Should" work on this Ali-express special.

SXOS, Hekate 4.0 and ReiNX. Autoincreases after 30 seconds. This is just an initial version to test as I don`t have one of those devices.

Payload will increase after 30 seconds. I just want to see if I`m on the right track with the thing.

Cheers.

Added Rebug SwitchME to method 1. Trinket payloads should work. Made a mistake with earlier method 1 graphic. Now updated.

Silly me!

Method 3 rebug SwitchME added.

So does this cheaper alternative have the same features as a trinket?

This post makes me so sad for humanity.

It's like when I see arguing over "is this fork of atmosphere with memes and toxicity" better than "this fork of atmosphere made by an actual developer" or this "weird amateur collection of files based on atmosphere".. it just makes me shake my head.

My SwitchMe came! It works fine for uploading payloads, and it was very easy to swap over to from what I already had installed. My only issue is that I cannot figure out how to reflash the payload after one has already been uploaded... I've allowed it to boot into the Hekate menu, and then I press the button through the back of my case twice. After that, nothing happens. The best I've been able to get Windows to do is throw a "USB Device not recognized", and that's after pressing the button many more times than twice. @mattytrog @evilsperm am I not getting the timing right? This is kinda a deal-breaker, it's gonna suck being stuck on Hekate 4.0 forever!

No you aren`t.

When on your switch main screen, make sure nothing is connected to USB (no computer or charger)

Double-press and THEN reconnect. Trinketboot should pop right up.

Ok, that works perfectly! Not sure where I got the idea of my way of doing it. Thanks a ton, very glad to finally not have to open my Switch up ever again!

Hi guys, i wanted to do method 3 with a trinket m0, but i removed the resistance of point 2 (trinket soft reset) without doing it on purpose .. My console works fine but i can't get it to work my trinket m0..

How can fix it? I still have resistance but it is too small, I can't put it back... :(

Il doit être là.

Pouvez-vous attacher le condensateur à une autre partie de la trace? Ou connectez simplement le Trinket et mettez le condensateur là? La valeur est 4.7uF

Translated. Can`t you connect to a different part of the trace?

It's a capacitor or résistor? Does the capacitor have a polarity?

I can't put up a picture, i'm a too younger member for this... :/

Ok so, i connect the down pad to the capacitor and the capacitor to the trinket, and the up pad? It's ground, there is a hole in the circuit no?

The capacitor seems dead.. I can't solder anything to it. Can i replace with a capacitor 4.7uf-35v radial?

Not something I would do.

You are better off getting a proper 0402 size one. Or get someone else to replace the capacitor.

What kind of battery drain would I be looking at for a method 3 install? Would the battery still be draining with the console turned completely off? Thanks!

I do not understand, yesterday my console started normally, even without the capacitor. This morning, it does not light anymore .. With or without trinket.

Only one capacitor can do that?

Depending on which capacitor is missing, I hope you haven`t caused the internal pin 5 (VCC-IN) M92T36 voltage to climb too high and pop it.

The capacitors are easy to change if you are careful and you have a good soldering iron. I buy mine in packs of 100 from RS components
