+
+Split Keyboard specific options, make sure you have 'SPLIT_KEYBOARD = yes' in your rules.mk
+
+* `#define SPLIT_HAND_PIN B7`
+ * For using high/low pin to determine handedness, low = right hand, high = left hand. Replace 'B7' with the pin you are using. This is optional and you can still use the EEHANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses.
+
+* `#define USE_I2C`
+ * For using I2C instead of Serial (defaults to serial)
+
# The `rules.mk` File
This is a [make](https://www.gnu.org/software/make/manual/make.html) file that is included by the top-level `Makefile`. It is used to set some information about the MCU that we will be compiling for as well as enabling and disabling certain features.
* Unicode
* `BLUETOOTH_ENABLE`
* Enable Bluetooth with the Adafruit EZ-Key HID
+* `SPLIT_KEYBOARD`
+ * Enables split keyboard support (dual MCU like the let's split and bakingpy's boards) and includes all necessary files located at quantum/split_common
This enables [key lock](feature_key_lock.md). This consumes an additional 260 bytes.
+`SPLIT_KEYBOARD`
+
+This enables split keyboard support (dual MCU like the let's split and bakingpy's boards) and includes all necessary files located at quantum/split_common
+
## Customizing Makefile Options on a Per-Keymap Basis
If your keymap directory has a file called `rules.mk` any options you set in that file will take precedence over other `rules.mk` options for your particular keyboard.

+
+
+This is a split 40% ortho board. It is the exact same footprint and the Let's Split keyboard by wootpatoot. This board has USB-C / RGB Underglow / and is all on-board. Meant as a drop-in replacement for the V2 Let's Split.
+
+Keyboard Maintainer: [Christopher Poole (That-Canadian)](https://github.com/That-Canadian)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make lets_split_eh/eh:default
+
+See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.
