+# Bluetreus - a conversion of an Atreus to use a Bluetooth microcontroller
+
+I have created a keymap for this with Bluetooth control on layer 2 so that you
+can switch the keyboard between auto, USB only, and Bluetooth only.  I'm
+working on fixing turning on auto by default, but have still not succeeded.
+
+To build it and flash it, do:
+
+```
+make atreus/feather:clash:flash
+```
+
+## Wiring it up
+Physically, SDA to pin 13 on the new board are connected to what 9-1 were
+connected to on the old board.  Pin 0 from the old board is brought over to the
+other side with a jumper wire to pin a2. TX, RX, A5, A4, A3 on the new board
+connect to what a0 to 12 connected to on the old board. GND attaches to g.
+You have to bend some of the pins at about a 45 degree angle to make them line up.
+Here's a side view of what the most bent pins look like:
+![Side View](https://i.imgur.com/S6ngibe.jpg)
+Here's a top view, USB port down, wireless antenna up. Note: the USB port orientation is opposite what it used to be.
