[Limited] - merro60 PCB

Created by u/darth_domo

This PCB is designed with additional cuts to allow you to gummy o-ring mount without having to modify your 60% case or file your PCB. 

Comes in USB-C and JST compatible with Universal daughterboard version.

Extra compatible plate available.

SPECIFICATIONS -

• solder PCB for MX and ALPS switches

• atmega32u4

• USB-C (& unified daughterboard footprint / connections if you choose to add later)

• 60% form factor

• layout options

  • stepped / full caps lock

  • full / split backspace

  • ansi / iso enter

  • full / split left shift

  • full / split right shift

  • ansi / tsangan bottom row with 10u spacebar option

• south-facing switches

• no LED / RGB

• single flex-cut mounting tab under the spacebar to ensure PCB can't "fall out" under extreme circumstances (I don’t recommend cutting fr4, but if done safely, the cut-out area is made large enough that the tab could be removed and the case post shouldn’t interfere with the pcb)

• possible to use screw-in stabilizer for spacebar (refer to build guide)

Note: we have noticed many customers are confused regarding what JST breakout means. It means that the PCB does not have a USB C port directly soldered on, but instead breaks out the USB port onto a separate board (called the daughter board). So, both options are USB C except one has the port soldered on and the other as it on a separate part.

JST breakout is advantageous because the USB port location on a keyboard case is not required to be fixed to a particular location such as the left side of the keyboard. It also reduces the likelihood that your PCB will be unfunctional due to the separation.

The footprints for both a JST port and a a USB C port are present on both of the models, but each has only one option pre-soldered on.
