1# Demod LM
2
3A low-profile number pad and sold by Keebio. [More info at Keebio](https://keeb.io).
4
5* Keyboard Maintainer: [Bakingpy/nooges](https://github.com/nooges)
6* Hardware Supported: Demod LM PCB with STM32G431 microcontroller
7* Hardware Availability: [Keebio](https://keeb.io)
8
9Make example for this keyboard (after setting up your build environment):
10
11 make keebio/demod_lm/rev1:default
12
13Example of flashing this keyboard:
14
15 make keebio/demod_lm/rev1:default:flash
16
17See 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).
