I’m gonna go w/ .5mm. :-)

Thank you very much appreciated

So you need some extra resistance for the Toshibas?

Hi guys, may i ask about this ribbon cable. Can I still solder the CPU wire from RP2040 to the blue arrow ? I accidentally broke the one on red arrow.

Could be that. Like 80 Ohm instead of 47. The wire length really shouldn't matter. But Toshiba is pretty stubborn, you could just get lucky. Once you have several boots, the statistics works for you. First glitching can be long, up to few minutes.

Yes, both central wires should go same place, you can check that.

There is waveshare zero schematics for details. The closest 4 caps around the chip are 100nF

0.5mm pitch confirmed

If I take AO4620 mosfet will it work normally?

Exciting work!
Can finally make use of my Lite and/or OLED as nicer versions of emulator handhelds.

For those trying to save space and not wanting to remove buttons or the usb port - This should also work,

this looks amazing, thank you for the link!

I might ask a super stupid question. Is it possibly to talk with their rp2040 from the Switch to update the firmware without opening it to update via the usb?

Confirm working on oled
Super fast boot, faster than oled v5
nand sk hynix
extra long wiring left due to possibly need to locate in another place
next step fit that monter inside
Thanks again to the privileged minds who made it possible.

yes, that was in my future plans. this requires really good design to avoid soft-bricks during the update like hwfly. (I have one)

hi can you tell me on witch pad the wire is soldered on the v2 flex cable Pad 3 or pad 4? Also is it the same pad on flex cable v1? Thank you!

pad 3 and 4 goes to the same trace

the rp2040 update function without opening the console will be nice

Also i don’t understand mosfet installation..some pictures show mosfet soldered to both left and right apu and other show mosfet just soldered to left apu cap..does just the left apu cap works? Thank you

I bet guides and video guides will be made

Guys, I think I managed to fit rp2040 in switch lite (cuz I only got lite).
Just need to cut off a little bit from the plastic part between ZR and R button, and from the back cover.
It seems the type-c is just of the same height as the speaker.
And it closed perfectly with the prussure of the screws.
