Chiisai Firmware Builds

Chiisai is a Pro Micro-compatible wireless keyboard controller designed by Clickety Split. It is built together with the shield target for the selected keyboard and hardware revision.

Board Target

Use the qualified ZMK board target:

clickety_split_chiisai/nrf52840/zmk

ZMK build configurations and metadata may also use the equivalent short form:

clickety_split_chiisai//zmk

Neither form changes the selected Chiisai hardware. The keyboard shield still determines the physical layout, revision, and half.

Choose the Keyboard Shield

Select the shield matching the keyboard connected to Chiisai. Current Clickety Split support includes the Leeloo family, with product-specific guidance on the following pages:

• Leeloo Firmware Builds
• Leeloo-Micro Firmware Builds

Local Build Example

From the ZMK workspace root:

west build -p -s app \
  -d build/<name> \
  -b clickety_split_chiisai/nrf52840/zmk -- \
  -DSHIELD=<shield_target>

Build and flash the matching firmware for both halves of a split keyboard.

Important Notes

• Use the shield target matching the physical keyboard revision.
• Use the correct left or right firmware for each half.
• Some features require a Chiisai-specific Clickety Split configuration.
• Where applicable, the display is defined directly by the keyboard shield. Do not add a separate display shield unless the product instructions explicitly require one.
• A settings reset may be required when changing between materially different configurations.

Recommended Build Path

The public Clickety Split GitHub configuration and GitHub Actions workflow will be linked here after final validation of ZMK with Zephyr 4.1.
