Keychron V2 Max is the latest version of the popular Keychron V2. New in this version is 2.4 GHz wireless through the included Type-C and Type-A receivers that are stowed directly in the back of the board. The V2 Max includes their latest sound-absorbing foam that creates a pleasant typing experience and is available in fully assembled versions. Similar to the original V2, the Max works great for both macOS and Windows due to their physical toggle that allows for quick keymap layer changes.
