+# Nebula12B
+
+This is a micropad layout PCB. It supports VIA, full per-key RGB and underglow RGB. This is revision B.
+
+* Keyboard Maintainer: [Yiancar](http://yiancar-designs.com/) and on [GitHub](https://github.com/yiancar)
+* Hardware Supported: A micropad with ATMEGA32U4
+* Hardware Availability: https://spaceholdings.net/
+
