+# UD40_Ortho_Alt
+
+![UD40_Ortho_Alt](https://i.imgur.com/NnGIo0O.png)
+
+The UD40_Ortho_Alt PCB is a modified layout for the UD040. It's similar to traditional ortho but the bottom row keys are larger than 1u. 
+
+* Keyboard Maintainer: [Nasp](https://github.com/npspears)
+* Hardware Supported: UD40
+* Hardware Availability: MyKeyboard.EU
+
+Make example for this keyboard (after setting up your build environment):
+
+    make checkerboards/ud40_ortho_alt:default
+
+Enter the bootloader by shorting GND and RESET just above the Atmega MCU.
+
+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).
