+# EC 23U
+
+![EC 23U PCB](https://i.imgur.com/G6QK1kU.png)
+
+Open source numpad Electrostatic Capacitive PCB.
+
+* Keyboard Maintainer: [cipulot](https://github.com/cipulot)
+* Hardware Supported: EC23U
+* Hardware Availability: [Github](https://github.com/Cipulot/EC23U)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make cipulot/ec_23u:default
+
+Flashing example for this keyboard:
+
+    make cipulot/ec_23u: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 3 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Physical Boot0 pins**: Short the Boot0 pins on the back of the PCB while plugging in the keyboard
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
