1# KMAC PAD
2
3![kmac_pad](https://i.imgur.com/4P1ybgNl.jpg)
4
5KMAC PAD is a num pad keyboard.
6It can be used independently, but can also be used by connecting with KMAC keyboard case.
7
8* Keyboard Maintainer: [talsu](https://github.com/talsu)
9* Hardware Supported: KMAC PAD
10* Hardware Availability: http://www.kbdmania.net/xe/news/5232321
11
12Make example for this keyboard (after setting up your build environment):
13
14 make kmac_pad:default
15
16Flashing example for this keyboard:
17
18 make kmac_pad:default:flash
19
20See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
21
22## Bootloader
23
24The PCB is hardwired to run the bootloader if the key at the `FN` position (the only key in first row) is held down when connecting the keyboard.

31### Switch Pins
32
33The FN key in the `Row 0` is directly connected to the E2 pin.
34The rest of the rows below that use MATRIX. (`Row 1 ~ Row 5`)
