1. DragonMMC replaces the stock MicroSD and NAND boards, and adds a slide switch to choose between up to 3 MicroSD cards/NAND modules. This slide switch protrudes slightly from the original MicroSD card slot, while a replacement kickstand houses 3 MicroSD card slots. Installation does not require soldering, but will require some disassembly of your Switch. All required tools will be included. Removal of the heat shield is currently required. Addons for the DMMC are planned, including fully internal Bluetooth audio streaming, and you can easily make your own thanks to the expansion connector and solderless USB passthrough. (Note that the DMMC itself has no USB capabilities and only passes the USB lines to the expansion connector.)

    DragonMMC is modular, with 3 NAND module slots available. An adapter module for the OEM NAND is included. Extra NAND modules of 64GB and 256GB will be available on the web store. The modules are snap-in and do not require soldering. An MCU handles NAND module and MicroSD card detection, as well as safe switching. The slide switch can be moved at any time to change the desired NAND module and MicroSD card. A restart or power cycle of the console will be required to enact the changes. If the selected MicroSD slot or NAND module is empty, DragonMMC will look for the next populated slot and enable it instead.

    DragonMMC will be based on the ESP32-PICO microcontroller. More info to come soon!

    Been waiting for the announcement for a while; now people can see the amazing work you do, you've helped my project so much too!

    It's also awesome that ReLoad will be the first modchip to control it!

    I'm a bit confused. Would this require you to autoRCM your switch? Or does it have some way around that?

    It's not required, no. RCM can be entered in a few ways, including removing the NAND chip or powering it down completely. With a programmed delay on boot before a NAND is enabled, RCM can be entered without changing the NAND itself at all.

    Will you be selling a seperate heat shield to replace the stock one or is there plans to try to have everything fit without needing to remove the heat shield?

    This looks genius and I was waiting for option to connect eMMC in place of microsd slot. :grog:

    I can't make any promises, but I am going to try to get custom heat shields made. I have no idea yet what the cost would be yet though - to get my own kickstand hinges made I think it ended up costing me around $500 for 1000, and a heat shield would be a lot more complex.

    @mattytrog " I'm hoping to pursue some on-console solutions for NAND cloning/resizing/etc. but I'm not much of a software guy" sounds like your time to shine ;P

    Why not?

    Could add nand resizing features...

    Let it parse a keys.txt file or something. Forget about it getting keys. Keys would need to be gotten by lockpick to avoid excess stack usage. Basically porting dd

    Good to see you again buddy. Out of curiosity, what modchips does SWITCHBOOT run on, and how many of them have I2C support?

    This is so cool! I love the fact that it even has it's own case. This is looking good!

    What do you mean by "it's own case"? :unsure:
