# Planck A compact 40% (12x4) ortholinear keyboard kit designed by OLKB and sold by Drop. A complete hardware rework of the rev6 Planck PCB, with support for up to 8 rotary encoders. [More info on qmk.fm](http://qmk.fm/planck/) * Keyboard Maintainer: [Jack Humbert](https://github.com/jackhumbert) * Hardware Supported: Planck PCB rev7 * Hardware Availability: [Drop](https://drop.com/buy/planck-mechanical-keyboard?mode=guest_open) Make example for this keyboard (after setting up your build environment): make planck/rev7: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.

Multiple encoders can be used at the same time, and are zero-indexed (compared to being one-indexed on the PCB's silkscreen) in the `encoder_update_user(index, clockwise)` function: ``` ,-----------------------------------------------------------------------------------. | 0 | | | | | | | | | | | 4 | |------+------+------+------+------+------+------+------+------+------+------+------| | 1 | | | | | | | | | | | 5 | |------+------+------+------+------+------+------+------+------+------+------+------| | 2 | | | | | | | | | | | 6 | |------+------+------+------+------+------+------+------+------+------+------+------| | 3 | | | | | | | | | | 7 | `-----------------------------------------------------------------------------------' ``` If an encoder has a switch built-in, it's connected to the key at that location. On the default keymap, each encoder will play its own rising/falling tone sequence when rotated, and will reset the pitch after one second of inactivity.
