+# mf68_ble
+
+![mf68_ble](https://i.imgur.com/zuTyy7k.jpg)
+===
+
+Magicforce 68 with [replacement PCB](https://github.com/di0ib/tmk_keyboard/tree/master/keyboard/mf68) designed by [di0ib](https://github.com/di0ib).
+
+Keyboard Maintainer: QMK Community  
+Hardware Supported: [Feather 32u4 Bluefruit](https://learn.adafruit.com/adafruit-feather-32u4-bluefruit-le/)
+Please note: This is 32u4 and not M0
+Hardware Availability: [PCB files](https://github.com/di0ib/tmk_keyboard/tree/master/keyboard/mf68/pcb)  
+[MF68 thicc case files](https://github.com/harshitgoel96/mf68-case-thicc)  
+Story
+-----
+
+The story and the idea behind this mod is available on [my reddit post](https://www.reddit.com/r/MechanicalKeyboards/comments/7eiiht/guide_i_built_a_bluetooth_enabled_magicforce68_no/)
+
+Wiring
+------
+
+Below is how you wire the Feather to PCB
+
+![wire map](https://i.imgur.com/zYOjlTA.png)
+
+Make example for this keyboard (after setting up your build environment):  
+
+    make 40percentclub/mf68:mf68_ble
+
+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).
