+# LATE-9
+
+
+The LATE-9 is a multi-tap input keyboard based on mobile phones from the late '90s. LATE-9 is intended as a dev board with 18 buttons and an OLED screen, made by through-hole components only. With this, you can experiment QMK OLED capabilities with very little expense.

+
+See the project repository for gerbers.
+
+* Keyboard maintainer: [rookiebwoy](https://github.com/rookiebwoy)
+* Hardware supported: ProMicro, _Elite-C (not tested)_
+* Project repository: [LATE-9 on github](https://github.com/rookiebwoy/late-9)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make late9/rev1:default
+
+Flashing example for this keyboard:
+
+    make late9/rev1:default:flash
+
+
+When asked by the terminal, short with a metal wire the pins on the backside of the board highlighted as `RST` (one is the `RESET` and the other one is `GROUND`) to enter the bootloader and let the OS detects the device.
+After installing this firmware you can use Bootmagic to enter the bootloader while plugging in your LATE-9. By default it's the button on the upper-left of the keyboard.
+
+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 [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
