# kc60se * Keyboard Maintainer: [Blake C. Lewis](https://github.com/BlakeCLewis), [MechMerlin](https://www.github.com/mechmerlin) * Hardware Supported: KC60SE * Hardware Availability: PCB is no longer available ## Description: * 60% keyboard PCB; * supports ANSI, ISO, and HHKB layouts. ### Enter the Bootloader * As delivered, BOOTMAGIC_ENABLE = yes: * unplug keyboard; * while holding down 'Space' 'B', plug in USB cable and continue to hold for 8 seconds; * 'lsusb' should report 'Atmel Corp. atmega32u4 DFU bootloader' instead of 'feed 6060'; * in bootloader LEDs are off & keyboard does not work. * New firmware, BOOTMAGIC_ENABLE = lite: * holding down esc while pluging in usb. * Hardware way: * momentary jump pads 5 & 6 to enter bootloader; ### Compile the default keymap: make kc60se:default 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.

It is eaier than flipping the dip switches; ``` dip keys #1 #2 K41 K4C 1 1 1 1 both keys enabled 1 0 0 1 0 1 1 0 0 0 0 0 both keys disabled ``` ### ISP header next to the ATmega32U4: * if you can't get into bootloader, while keyboard is on, momentary jump pad 5 to pad 6 ``` 2 4 6 : : : 1 3 5 ``` ``` 1 - B3 MISO, column 13, square pad 2 - VCC 3 - B1 SCLK, column 7 4 - B2 MOSI, caplock led 5 - Reset | momentary jump 5 and 6 6 - Ground | to enter Bootloader ```
