Can R4 3DS work on Nintendo Switch or Switch Lite?
No, R4 card is for Nintendo 3DS and NDS serial machines, it doesn’t have compatibility to Nintendo Switch, even mention the Switch Lite and New Switch model. It only can be inserted to 3DS&NDS console slot.

However, an old R4 team(R4i-sdhc.com) produces one prodoct for Nintendo Switch hackable consoles, it is named R4s Dongle, or we call it R4s Switch as well. But it isn’t a flashcard or a modchip for Switch, it’s a usb dongle as a payload injector to boot custom firmware on Nintendo Switch, also includes a RCM Joycon Jig for turing the Switch to RCM mode before hacking.
R4s Dongle is as cheap as the R4 3ds, its major function is to launch CFW on Nintendo Switch to play free games and homebrews. It supports SX OS, Atmosphere, ReiNX and any other Switch custom firmwares. Currently, only Atmosphere supports cracking Switch 9.0.0 firmware consoles. So if you have updated Switch to the latest version, you can use the R4s dongle to boot Atmosphere 0.9.4 on Switch for homebrewing.

Plus, one important thing, R4s Dongle isn’t working on Every Switch, if you have a Switch Lite or New Switch with serial number start from XKW or XKJ. The R4s dongle isn’t compatible with them, because they are using a different processor, removing the old bootroom bug.

So, all in all, R4 3DS can’t work on any Switch, but R4s Dongle can support Nintendo Switch, it just can’t Jailbreak the Switch Lite and New Switch devices currently.

Then, let’s conclude.
• For Nintendo 3DS: R4 3DS works, the best flashcard to buy is R4i 3ds gold plus, the Italian seller Modswitchit and Italiamods has them to send you via free shipping.
• For Nintendo Switch:R4 card can’t work, but R4s Dongle supports it.
• For Switch Lite: Neither R4 3DS nor R4s Dongle support, nothing can work for now.
