+# Keychron C1 Pro V2
+
+![Keychron C1 Pro](https://i.imgur.com/Svdm4lph.jpg)
+
+A customizable 80% TKL keyboard.
+
+v1 is based on STM32L432 and v2 is based on STM32F402.
+
+* Keyboard Maintainer: [Keychron](https://github.com/keychron)
+* Hardware Supported: Keychron C1 Pro
+* Hardware Availability: [Keychron](https://www.keychron.com)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make keychron/c1_pro_v2/ansi/rgb:default
+    make keychron/c1_pro_v2/ansi/white:default
+    make keychron/c1_pro_v2/ansi/non_light:default
+
+Flashing example for this keyboard:
+
+    make keychron/c1_pro_v2/ansi/rgb:default:flash
+    make keychron/c1_pro_v2/ansi/white:default:flash
+    make keychron/c1_pro_v2/ansi/non_light:default:flash
+
+## bootloader
+
+Enter the bootloader in two ways:
+
+* **Bootmagic reset**: Hold down the key located at *K00*, commonly programmed as *Esc* while plugging in the keyboard.
+* **Physical reset button**: Briefly press the RESET button under the spacebar.
