The second ArrowPad was a conversion from a 21-key Genovation keypad. It used a 2 row x 11 column matrix.

Depending on which keymap you would like to use, you will have to compile slightly differently.
### Default
-To build with the default keymap, simply run `make default`.
+To build with the default keymap, simply run `make handwired/arrow_pad:default`.
### Other Keymaps
Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `<name>.c` in the keymaps folder, and see keymap document (you can find in top readme.md) and existent keymap files.
To build the firmware binary hex file with a keymap just do `make` with a keymap like this:
```
-$ make [default|pad_21|pad_24|<name>]
+$ make handwired/arrow_pad:[default|pad_21|pad_24|<name>]
```
Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
