+# BDN9-BLE
+
+![BDN9](https://cdn.shopify.com/s/files/1/1851/5125/products/[email protected]?v=1547909493)
+
+A handwired modified version of the Keebio BDN9 macropad to support BLE through the Adafruit Feather 32u4 Bluefruit LE.
+
+Keyboard Maintainer: [merlin04/KeyPCB](https://github.com/merlin04)  
+Hardware Supported: Adafruit Feather 32u4 Bluefruit LE  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make handwired/bdn9-ble: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).
