+# snampad
+
+![snampad](https://imgur.com/gallery/tPDHeB9?s=fbm)
+
+A small weekend project to create a numeric keypad for the few times I need such a thing.
+I created the schematics in Kicad, 3D printed the case, handwired the prototype, used some
+spare Zealios, Box Royals and SA keycaps.
+
+When I get some time I'd like to make a PCB for it.
+
+It uses a promicro controller and the reset button has been made availabe through a hole in the backplate.
+
+
+Keyboard Maintainer: [Peter Tillemans](https://github.com/ptillemans)
+Hardware Supported: Promicros are ubiquitous.
+Hardware Availability: This uses essentially spares from other projects
+
+
+Make example for this keyboard (after setting up your build environment):
+
+    make snampad:default
+
+See 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).
