# NOAH 65 keyboard
![NOAH](https://raw.githubusercontent.com/yulei/qmk_webusb_tool/master/public/noah.jpg)
This was the first 65% keyboard made by the Matrix team, it had the following features:
- per key rgb led
- 7 RGB led for caps, scroll , num lock and layer state indicator, or just play light animation effects
- ansi and iso layouts, and split spacebar supported
- pre-programmed bootloader which emulated usb stick to ease firmware updating
Keyboard Maintainer: [astro](https://github.com/yulei)
Hardware Supported: Matrix NOAH keyboard
Hardware Availability: [NOAH Keybaord](https://geekhack.org/index.php?topic=102300.0)
