This boards are being sold for parts but they are working. If you fully build a set of joy cons with this 2 you can connect them to your switch thru Bluetooth ur the actual dock system does not work due to the 2 locking tabs being broken/missing.

If you have spare locking tabs this should be an easy fix. I ended up picking 2 spare boards as I don’t have the spare parts.

Rh joycon board -GK9968

LH joycon board- 4jxgj9

I was using this and charging the joycons on a separate charger that actually worked just fine as one does charge on the switch but the other one doesn’t.
