+# Plexus75_HE
+
+![Plexus75_HE](https://i.imgur.com/niz4raR.png)
+
+The Plexus75_HE is a hotswap version of the Plexus75. Another difference is the included RGB underglow. What is the OG Plexus75? It is a 60% ortholinear keyboard based on the XD75 but instead of an all 1u bottom row the Plexus75 has a more traditional bottom row similar to reg. 60% boards.
+
+* Keyboard Maintainer: [Nasp](https://github.com/npspears)
+* Hardware Supported: Plexus75_HE PCB
+* Hardware Availability: https://www.checkerboards.xyz/Plexus75-Hotswap-PCB_p_46.html
+
+Make example for this keyboard (after setting up your build environment):
+
+    make plexus75_he:default
+
+To enter the bootloader, short the two pins just underneath the spacebar on the left side.
