-![DQz11N1G-DE Layout Image](https://u.cubeupload.com/ddklg/OPBN5q.jpg)
-
-# Default Layout for DQz11N1G-DE
-
-This is the layout corresponding to what the Maltron keyboard DQz11N1G-DE I
-own came with (using the original pre-installed controller).  Note that this
-differs from German Maltron layout as published on [Maltron's
-website](https://www.maltron.com/germany.html).  Use the photo above as a
-reference for the layout implemented here.
-
-I did not find any official documentation about the the Function Lock key on
-the original Maltron keyboards.  It seems that it implements some of the
-features that are documented for the one-handed Maltron keyboards.  Most
-keys don't send any keycodes at all when function lock is enabed.
-
-We instead map some of the Quantum keycodes (mouse keys and audio control)
-in the middle (keypad) section of the keypad, when Function Lock is enabled.

-# DQz11N1G
-
-![DQz11N1G](https://u.cubeupload.com/ddklg/OPBN5q.jpg)
-
-Firmware for a DIY controller replacement for one of the ortholinear contoured
-keyboards manufactured by [PCD Maltron Ltd](https://www.maltron.com)
-
-This work here in no way officially associated with PCD Maltron Ltd and comes
-with NO WARRANTY.  Modifying your Maltron keyboard as described below will
-certainly void your warranty and may cause damage to your keyboard.  Proceed
-at your own risk!
-
-* maintainer: [David Kuehling](https://github.com/dvdkhlng/qmk_firmware_dqz11n1g)
-* Hardware Supported: Maltron DQz11N1G with a replacement controller board
-  assembled as described below.  The work here is based on a german version
-  of the keyboard: DQz11N1G-DE.  I assume, but don't know for sure, that
-  minor or no changes at all are required to make this work on different
-  language versions of the keyboard.
-* Hardware Availability:
-  * [PCD Maltron Ltd](https://www.maltron.com), for the original keyboard
-  * 1x [Arduino Pro Micro](https://www.sparkfun.com/products/12640)
-  * 3x [SN74HC165](https://www.ti.com/product/SN74HC165)
-  * 1x DIL connector 2 rows a 17 pins.
-  * 19x pull-down resistors (10k Ohm),
-  * 4 LED current limiting resistors (not sure about the correct resistance,
-    using 470 Ohm here)
-
-Make example for this keyboard (after setting up your build environment):
-
-    make handwired/dqz11n1g:default
-
-## In Detail
-
-[PCD Maltron Ltd](https://www.maltron.com) manufacturs ergonomic keyboards
-that appear to be hand-wired internally.  For the Maltron DQz11N1G-DE
-keyboard that I happen to own, the keyboard matrix is wired to a 34-pin DIL
-connector.  This makes it rather easy to replace the proprietary
-controller-board with a self-made board based on the QMK firmware.
-
-I don't really like the default layout of my Maltron DQz11N1G-DE keyboard,
-and modding it to work with QMK allows me to adapt it to my needs.  It
-especially allows for the two space keys to assume different roles, thereby
-creating an additional easily reachable thumb-key.
-

-![DQz11N1G-DE keyboard matrix connector](https://u.cubeupload.com/ddklg/fjFXeL.png)
-
-### Replacement Keyboard Controller Board
-
-Due to supply chain problems, I decided to base this on an
-Arduino-compatible [Pro Micro](https://www.sparkfun.com/products/12640)
-board which is still easy to source.
-
-Unfortunately pin-count of the DQz11N1G-DE's keyboard matrix is way beyond
-the Pro Micro's available I/O pin count.  I'm using three 8-bit
-shift-registers ([SN74HC165](https://www.ti.com/product/SN74HC165) ) to
-connect the 19 colums of the keyboard matrix for readout.  Due to diode
-direction in DQz11N1G-DE we also need 19 pull-down resistors one for each of
-the utilized shift-register inputs.
-
-This is a design sketch of the replacement board this is based on.  Note how
-we need a custom matrix.c source file to deal with the shift register based
-keyboard readout.
-
-![Sketch of Keyboard Controller Board](https://u.cubeupload.com/ddklg/GBZgSf.png)
-
-This is how the assembled controller board looks like, on the right side you
-see the original PIC-based controller the keyboard ships with.

-connector for a reset switch to simplify flashing controller firmware)
