User Manual & Troubleshooting for Corne Choc V1

Firmware

Please fork zmk-config-crkbd. Changes made on our zmk-config:

CONFIG_ZMK_BLE_EXPERIMENTAL_CONN=y

Add CONFIG_ZMK_BLE_EXPERIMENTAL_CONN=y on config.h. This allows the bluetooth to connect to win 11 and some newer Mac series properly. Enables a combination of settings that are planned to be default in future versions of ZMK to improve connection stability. This includes changes to timing on BLE pairing initiation, restores use of the updated/new LLCP implementation, and disables 2M PHY support.

CONFIG_ZMK_POINTING=y

Supports mouse keys including mouse movement and scroll allow you to remap in Keymap Editor properly.

Firmware Compilation & Flashing

Battery

Different battery capacities are suited for different keyboard builds. Below is a guide to help you decide which battery to use based on your board's design and requirements.

Due to shipping restrictions, batteries cannot be shipped internationally. We can only deliver to adjacent countries via land transportation, such as Singapore, Thailand, Myanmar, and Vietnam. If we cannot ship a battery to your location, you will need to purchase it locally.

1. 500mAh Battery

  • Placement: Positioned below the PCB, resulting in a 3mm increase in overall board thickness.

  • Compatibility: Suitable for boards with or without a display.

  • Considerations: The increased thickness might affect the keyboard's overall profile but provides a longer battery life.

2. 140mAh Battery

  • Placement: Slotted under the MCU, with no increase in board height.

  • Compatibility: Best suited for boards without a display.

  • Considerations:

    • Adding a display along with this battery type increases the height of the MCU area, making it significantly taller than the keycap.

    • Not recommended for builds with a display due to this height discrepancy.

Steps to Procure the Battery Locally:

  1. Find a Local Seller: Locate a local electronics or battery supplier who can provide 303450 550mAh batteries.

  2. Request for Socketing: Once you have the batteries, you’ll need to ask the seller to socket them with PH2.0 connectors. This will allow you to easily connect the battery to your device without the need for soldering.

  3. No Soldering Required: No soldering is required on your end. Simply ensure that the batteries are socketed and ready to be connected.

  4. Assembling the Battery: Remove the five screws from the bottom plates. Slot in the battery as shown in the photo.
