+# Duck TC-V3
+
+Non official firmware for custom Korean keyboard made by Duck.  
+Group buy was run April 2018 via [geekhack](https://geekhack.org/index.php?topic=95335.0).  
+
+* Keyboard Maintainer: [MechMerlin](https://github.com/mechmerlin)
+* Hardware Supported: Duck TC-V3 ver 1.0 PCB, Atmega32u4, 74HC237D 
+* Hardware Availability: Wait until GB of the next revision
+
+Make example for this keyboard (after setting up your build environment):
+
+    make duck/tcv3:default
+
+**Reset Key:** To put the TC-V3 into reset, hold the top second most right key (`K0J`) while plugging in. 
+
+**CAUTION:** At this time 02/28/20 backlighting has not been tested fully and may not properly work. 
+
+See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
+
+## Hardware Notes
+
+The Duck TC-V3 PCB consists of:
+
+### Microchips
+* 2 74HC237D 3-to-8 line decoders
+* 1 Atmega32u4 microcontroller
+* 3 WS2811 LED controller
