+
+![EC980C PCB](https://i.imgur.com/KcnLdVFh.png)
+
+Replacement PCB for the Leopold FC980C.
+
+* Keyboard Maintainer: [cipulot](https://github.com/cipulot)
+* Hardware Supported: EC980C PCB
+* Hardware Availability: TBD
+
+Make example for this keyboard (after setting up your build environment):
+
+    make cipulot/ec_980c:default
+
+Flashing example for this keyboard:
+
+    make cipulot/ec_980c:default:flash
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 2 ways:
+
+* **Physical reset**: Long short the exposed pads on the top of the PCB
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
