# 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:
|
||
|
|
|
||
|
|
Here's a top view, USB port down, wireless antenna up. Note: the USB port orientation is opposite what it used to be.
