1) Please check your motherboard version number before purchasing! This version of BL Touch Kit is meant for 8-bit motherboards with version numbers that starts with V1.X.X. If your motherboard version number starts with V4.X.X, it means that it is a 32-bit motherboard which this kit is not compatible with.
2) This kit does NOT work with Ender 3 V2. Main reason being that the Ender 3 V2 comes with a 32-bit motherboard and the metal bracket with this kit will not fit on the Ender 3 V2. This kit is meant for Ender 3, Ender 3 Pro, Ender 5, Ender 5 Pro printers with 8-bit motherboards. BL Touch Kit for Ender 3 V2 available here.
