+# Bartlesplitt
+
+![Bartlesplit with the hub in the 3x6 setup](https://i.imgur.com/IoMpwylh.png)
+
+Bartlesplit is based on [Cheapino](https://github.com/tompi/cheapino) by Tompi.
+The original idea was to build a Cheapino with hot swaps, but it evolved into something more!
+
+At the same time I was working on Bartlesplit, a friend of mine suggested that we try to make a splithub, letting us avoid having the Pro Micro directly on the board.
+This is mostly a design choice, making each split less clutered.
+We have called the hub [The Japanese Connection](https://github.com/Kyrremann/the-japanese-connection) since it's relying on the Japanese duplex matrix.
+
+One of the main feature of the board is the built-in tenting, so you don't need to make a case to get simple tenting.

+    make minimon/bartlesplit:default
+
+Flashing example for this keyboard:
+
+    make minimon/bartlesplit:default:flash
