# Information for Various BastardKB Hardware ## Handedness Pin on Elite-C Holder The [Elite-C Holder](https://github.com/Bastardkb/Elite-C-holder) supports setting [handedness by pin](https://docs.qmk.fm/features/split_keyboard#handedness-by-pin) on pin F1 of an Elite-C. To utilise this, you must be using an Elite-C compatible development board (with the bottom 5 pins broken out) and install the necessary resistor. The following firmware configuration can be made in your keymap directory: ```Makefile # rules.mk PIN_COMPATIBLE = elite_c ``` ```c // config.h #pragma once #define SPLIT_HAND_PIN F1 #define SPLIT_HAND_PIN_LOW_IS_LEFT ```
