Is there any R4 card working on Nintendo Switch 6.2.0?

Nintendo Switch latest firmware 6.2.0 came some days ago, this is not a Big update because no new features or functions are being added, but for the hacking scene, this system version is patching a lot of stuff. That is, all the custom firmwares, SX OS, Atmosphere, ReiNX, RajNX, and any other one are Broken on the newest Nintendo Switch V6.2.0. That's to say, because all the flashcarts which are being worked on the Switch, their major function is to boot CFW on the Nintendo Switch. If the CFW isn't working any more, they are useless too for hacking the Nintendo Switch console.
So, no R4 or no flashcart is working on Nintendo Switch 6.2.0 firmware. On the other hand, there is a R4 card support hacking Nintendo Switch console indeed. It is the R4s dongle.
Introduction
R4s Dongle is made by the R4i-sdhc.com, which has releases many DS/3DS R4 cards for hacking those Nintendo handheld machines. Then in August of 2018, the team develops and launches their newest modchip or flashcard for the Nintendo Switch machine. However, the R4s dongle is different from any R4 cards, it's not a flash cartridge should be insert to Switch slot as the real game card, it's a toolkit for Nintendo Switch users. 
R4s Dongle includes a usb dongle(payload injector) and a joycon jig(rcm jig) for hacking the Nintendo Switch. To play Nintendo Switch games with it, users should insert the usb dongle to the usb port of Nintendo Switch and use it to boot Switch custom firmwares(SX OS, Atmosphere, Reinx), then free game play can be available on the CFW.
As the official site introduces, the R4S dongle is a USB-C dongle that is a plug and play solution to inject the necessary RCM payload to boot into custom firmware. It allows you to hack Nintendo switch with loading custom firmware.
