Existing support for encoders in ZMK is focused around the five pin EC11 rotary encoder with push button design used in the majority of current keyboard and macropad designs.
:::note
Encoders are currently only support on the left/central sides of splits. For progress on this, see [#728](https://github.com/zmkfirmware/zmk/pull/728).

## Enabling EC11 Encoders
To enable encoders for boards that have existing encoder support, uncomment the `EC11_CONFIG=y` and `CONFIG_EC11_TRIGGER_GLOBAL_THREAD=y` lines in your board's .conf file in your `zmk-config/config` folder. Save and push your changes, then download and flash the new firmware.
