+![M48](https://i.imgur.com/QLuCAlWh.jpg)
+
+A  (12x4) ortholinear keyboard that can be hand wired or using a pcb.
+
+* Keyboard Maintainer: [Alin Elena](https://github.com/alinelena) ([@drFaustroll on GitLab](https://gitlab.com/drFaustroll))
+* Hardware Supported: custom pcb [see](https://gitlab.com/m-lego/m48) STM32F401 from we act (rev1)
+* Hardware Availability: [custom how to](https://gitlab.com/m-lego/m65)
+
+
+Make example for this keyboard (after setting up your build environment):
+
+    make mlego/m48/rev1:default
+
+Flashing example for this keyboard:
+
+    make mlego/m48/rev1:default
+
+To enter flashing mode, press Lower+Raise+1 or Lower+Raise+0 also on microcontroller keep pressed BOOT0 and then NRST, release NRST and then after 0.5s or so  release BOOT0.
+
+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).
