+# navpad 1.0
+
+![navpad_10](https://imgur.com/zxElDdWh.jpg)
+
+Useful and easy to build numpad with nav-cluster
+
+* Keyboard Maintainer: [yushakobo](https://github.com/yushakobo)
+* Hardware Supported: NavPad 1.0 PCB, Pro Micro
+* Hardware Availability: https://shop.yushakobo.jp/products/navpad-10
+
+Make example for this keyboard (after setting up your build environment):
+
+    make yushakobo/navpad/10:default
+
+Flashing example for this keyboard:
+
+    make yushakobo/navpad/10: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 reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available

+# navpad 1.0 with Helix (Right hand side)
+
+![10_helix_r](https://imgur.com/ehTI37h.jpg)
+
+Navpad connected with helix keyboard (Right Side)
+
+* Keyboard Maintainer: [yushakobo](https://github.com/yushakobo)
+* Hardware Supported: Navpad 1.0 PCB and Helix PCB, Pro Micro
+* Hardware Availability: https://shop.yushakobo.jp/products/navpad-10
+
+Make example for this keyboard (after setting up your build environment):
+    
+    make yushakobo/navpad/10_helix_r:default
+
+Flashing examples for this keyboard...
+
+Helix side:
+    
+    make yushakobo/navpad/10_helix_r:default:avrdude-split-right
+    
+Navpad side:
+
+    make yushakobo/navpad/10_helix_r:default:avrdude-split-left
+
+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 reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
+* **Keycode in layout**: Press the key mapped to `RESET` if it is available
