+
+[Siemens_tastatur](https://i.imgur.com/mQY4CQA.jpg)
+
+A Blue Pill STM32F103C8T6-based Converter board for a very very old keyboard.  
+
+Keyboard Maintainer: [Yiancar](http://yiancar-designs.com/) and on [github](https://github.com/yiancar)  
+Hardware Supported: Blue Pill STM32F103C8T6  
+Hardware Availability: Custom PCB available, contact me  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make converter/siemens_tastatur:default
+
+Unplugging and replugging the keyboard is necessary after a firmware update.
+
+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).
