    - Solenoid Switch
    - PCBs, daughterboard, JSTs and other electrical components
    - Battery
    - Rubber feets
    - LED diffusers
   
    Please note the following are NOT included:
    - Keycaps
    - Stabs
    - Switches
   
   
2. How many units will there be?
   
    This is a group buy. No further GB round is planned yet.
   
       
3. Do you have a discord? How to contact you?
   
    You can discuss about the NP-R on Flatbrains! discord (https://discord.gg/xmbd2FTM2b). You can also contact me directly (.bagri) on discord, or on my instagram (https://www.instagram.com/bagri_shoot).
   
   
4. Have you designed other things?
   
    My first project was the GMK Alt grrrrr kit (https://geekhack.org/index.php?topic=123393.0).
    Flatbrains! have designed many other projects including the Plaket XL (https://geekhack.org/index.php?topic=123610.0).


Based on IC form questions:

- About adding PC option: This won't be implemented at this stage for cost reasons.

- About the button and knob: To clarify: the button is a toggle on/off for the solenoid. The knob has 3 fixed positions to change between 3 layers. That doesn't prevent you from mapping additionnal layers on the keys like a regular keyboard.

- Regarding Mac/Windows compat: Yes, it is, like any other ZMK board.

- Regarding Southpaw and bluetooth: Yes, both included. Refer to the specs :)

- Regarding bluetooth vs wired only: The NP-R still be usable if you physically disconnect the battery and decide to use it only wired. It also works in wire mode with the battery connected.

- Regarding hotswap PCB: Unfortunately no. There are other electrical components to be soldered to the build besides the switches, so in my view there is little point in providing a hotswap PCB.

- Regarding extra parts: The below parts will be available to purchase as extras:
  • plate (orange and lime color),
  • button cap (orange and lime color),
  • PCB (including DB and all JST),
  • Rocker switch, rotary switch, solenoid and other electrical components,
  • battery (for countries where it’s allowed to ship battery alone),
  • weight (raw alu and STS),
  • Feets
