Awesome render! I'd say your tweaking of skills is paying off! Quick question, will the USB-C end be sticking out of the unit?

There's a cap that covers the connector and completes the game card form factor when the DI is not in use, so nothing will be sticking out.
Can I get my card is super bright pink?
Also, can I ask for a USB-C female port? Since I noticed these male ports sticking out breaks super fast if not extra secured with something on top of it.
Pink and purple seem to be popular colors, if the first batch moves well and I can afford injection molding I'll make sure some pink and purple get made.
Regarding the male Type C plug, I think you might be surprised with how strong this one is. Typical Type C connectors only have the pins welded, along with some small support material on either side siilar in size to the pins. With the DI, the "support" for the connector is the entire casing of the plug, so it's far stronger than typical male Type C connectors. The part number is CX60-24S-UNIT if anyone is interested - it's the only Type C connector I could find anywhere that is designed to have the casing welded to the PCB for added strength.
I didn't think so but I wanted to be sure! Amazing effort on this. If more individuals (including myself) practiced way more at learning certain tech aspects we would see so many, many more great things. All about where you decide to put your interest an effort! Again, serious love for this project! Simply impressive. Thanks for updates when available!There's a cap that covers the connector and completes the game card form factor when the DI is not in use, so nothing will be sticking out.
Diodes arrived today, just did the swap on one of the test units.
IT WORKS! All hardware issues have been solved and are tested and working. Software-wise, flashing works, bootloader works and I have smaller payloads like SX's injecting nicely. Some awesome people are helping me squeeze the larger payloads down to fit. Likely some form compression will be implemented, making it nice and easy to get any payload to fit.
I'm going to swap the diodes on the rest of my tester units while my Switch is charging, then take a video of everything working.
So, before the end of the week I'll be submitting an order for 525 DIs to PCBWay. It'll take about a month for them to be made and shipped to my door, at which point I'll prep 25 for my testers and get them sent off priority. I'll keep assembling more as they spend a few days testing them out, and then I can start shipping them to everyone!
Also, if you're ever building your own board, pay attention to the spec sheet of your diodes! Even 0.5mA of reverse leakage current can be enough to ruin your day. Most diodes are skewed towards one of two use cases: low forward voltage, OR low reverse leakage current, not both!

How much space will we have for payloads? I really only plan on using one, Atmosphere's fusee-primary. Any other payloads I use so rarely I'd just use my PC to send them.
Depends how we go about it. We're thinking now that chainloaders might work better. So it'd be something like this:
Firmware 1 (default shipped): DI boots whatever .bin it finds first in /DragonInjector/ on your SD root. You could choose to use ArgonNX or the new Hekate or whatever you want in this manner.
Firmware 2 (optional): DI boots whatever .bin it finds first in /DragonInjector/Payload_1/ through /DragonInjector/Payload_8/. The folder selected would be determined by the Payload button on the DI itself, with the status LED blinking, for example, 3 times when you select the Payload_3 folder. I'd be programming in a way to set the maximum number of payloads (probably by holding the payload button) so if you only use 3 different payloads, you wouldn't have to cycle through all 8 slots.
I promised a video tonight, and here it is:

I hope there's no other revisions....I don't NEED this but I'd like to have one (or two).

The contacts are not electrically connected to anything, and I've deliberately kept any traces completely out of the path of the slot pins. They are only there to look nice and so the pins don't wear down the PCB. The "trigger" pin that tells the Switch a game card has been inserted has also been separated from ground, so your Switch will have no idea anything is in the slot.
TL;DR - no risk to your Switch at all.
What's the point of this? Use a game card slot for what it's for, GAMES!Hey everyone! I want to share a project I'm currently working on - a payload injector with the form factor of a Switch game cart!
As I seem to always forget to bring my phone, cable, OTG adapter or dongle with me, and I'm not a big fan of AutoRCM, I started thinking - wouldn't it be great if I could just store my jig and dongle inside my Switch? I don't really like the idea of opening my switch and soldering to it for warranty/resale reasons, and my card slot is always empty because, well, we live in the age of digital. Thus, DragonInjector was born.

So, what is it and what can it do?
- Stores your payload dongle inside your Switch game cart slot.
- Always have your RCM jig on you as it's stored in the cap.
- Inject your payload with a USB Type C connector so no adapters are needed.
- CR1216 power source good for 250+ injections.
- Forget it even exists until you need it.
- Easy access to the SWD and SWC pads so you can reprogram it for whatever you like, including non-Switch stuff.
- Switch between multiple payloads with the press of a button.
- Uses the same ATSAMD21 MCU as the Trinket M0.

How far along is the project?
The latest prototype PCBs will be delivered this week. If the prototype works well, I'll post a video of it in action and get tester units sent out. (All tester positions are filled, sorry!)
When and where can I get one?
Once they're ready, I'll be selling them on tindie. A link to the product page will be put in my signature, and I'll make a post in the selling forums. I'll let everyone know when that happens.
Is there a place we can chat about the project or ask questions that aren't fit for this development thread?
Yes! There's a Discord server where I post progress, renders, photos, and other things quite often. You can find it here:
Shipping to my country is expensive. Can I arrange combined shipping with other buyers?
Channels have been added to the Discord server to help organize this. If your country is not listed, @ me there and I'll add it.
Thanks to everyone for all the support so far! I've honestly been blown away by the amount of interest this project has gotten since I first posted here and can't wait to deliver something great for you all.

Plus knowing it'll be more than an RCM loader, why bother?
RCMLoader and autorcm ftw.
What's the damn point?
Respect people's project, it is an one of a kind project that fit into the gamecard slot of a switch.
Again the cartridge slot is meant for games.
This is going to cost more than RCM loader so why even fucking bother?
--------------------- MERGED ---------------------------
Plus and RCM loader has a way better battery life than this, and it's small enough to carry around anywhere.
This is just pointless.
Cause it is unique no need to be rude, these project are consider rare, all the RCMloader/NS Atmosphere dongle out there can't be fitted into a gamecard slot. Anyway go away, respect MatinatorX's work.
What's the point of having it to be able to fit in the game card slot? Again that slot is meant for games..
not like you can shoot the payload through the game card slot you still have to plug it into the USB c port.
Useless product.
