![kp21 &mdash; full grid layout](https://ae01.alicdn.com/kf/HTB1d.txfHsTMeJjSszhq6AGCFXaF.jpg?size=35021&height=662&width=1000&hash=62b3a453686e2154dc51a7af67495e28)

ps2avrGB based number-pad sold fully assembled by YMDK on Aliexpress.

Keyboard Maintainer: [QMK Community](https://github.com/qmk)  
Hardware Supported: Atmega32A
Hardware Availability: [AliExpress](https://www.aliexpress.com/item/21-Key-NPKC-Programmable-Cherry-MX-Kailh-Gateron-Switches-Mechanical-Keyboard-Numpad-Free-shipping/32812732361.html)

Make example for this keyboard (after setting up your build environment):

    make ymdk_np21:default:program

Plugging the board in while pressing 'Top Left Key' (USB on top) will force it to boot bootloader without loading the firmware.

The code for NP21 is a minor edit of jj40.
