According to Nordic's documentation, the DC/DC regulator is more efficient than the LDO regulator, so this is enabled by default. The following boards do not support this mode and were not changed: - nice_nano - nice60 - nrfmicro_11, nrfmicro_13 - nrf52840_m2 - bluemicro840 I could not find schematics to confirm whether the following boards support this mode: - bt60_v1, bt60_v2 - bt65_v1 - bt75_v1 - corneish_zen_v1, corneish_zen_v2 - pillbug - puchi_ble_v1 - s40nc commit 8f5c7bb Author: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Date: Mon Feb 26 05:52:14 2024 +0000 chore(deps): bump pre-commit/action from 3.0.0 to 3.0.1 Bumps [pre-commit/action](https://github.com/pre-commit/action) from 3.0.0 to 3.0.1. - [Release notes](https://github.com/pre-commit/action/releases) - [Commits](pre-commit/action@v3.0.0...v3.0.1) --- updated-dependencies: - dependency-name: pre-commit/action dependency-type: direct:production update-type: version-update:semver-patch ...

Saved ~200uA avg on another board with a 3t toggle switch commit af90882 Author: Peter Johanson <[email protected]> Date: Wed May 1 11:01:32 2024 -0700 fix: Initialize sideband kscan in APPLICATION. * In order to be sure the rest of the system is fully ready before intializing, because init may result in immediate events being triggered when used with toggle direct kscan inner devices. commit d1ad347 Author: German Gutierrez <[email protected]> Date: Mon Apr 29 18:22:40 2024 +0200 fix: shortening keymap_soft_off behavior node * Shorten the soft off node in order for it to work across splits. commit 0d3a4b7 Author: Jarryd Tilbrook <[email protected]> Date: Thu Apr 25 22:26:26 2024 +0800 fix(underglow): Correctly set underglow state This fixes a bug introduced in zmkfirmware#2244 commit 4d56685 Author: Pablo Martínez <[email protected]> Date: Thu Apr 25 10:55:42 2024 +0200 fix(rgb): auto-off logic commit f4a070a Author: Sadek Baroudi <[email protected]> Date: Sun Apr 21 12:37:47 2024 -0700 fix(boards): nrf boards missing SPI in pinctrl and dtsi, requiring users to manually define in their shield definitions if they wanted to use SPI commit 16e92cf Author: Peter Johanson <[email protected]> Date: Thu Apr 18 06:38:46 2024 +0000 fix(behaviors): Add multiple soft-off instances properly. * Properly pass the node id for the unique soft-off behavior instance when defining it. commit e22bc76 Author: Keeley Hoek <[email protected]> Date: Sun Apr 7 07:05:51 2024 -0400 fix(hid): Correct off-by-one buffer overflow with NKRO commit a9021de Author: Cem Aksoylar <[email protected]> Date: Tue Apr 9 10:25:33 2024 -0700 fix(docs): Add wakeup-source to split new shield example commit dfc6dc8 Author: Cem Aksoylar <[email protected]> Date: Tue Feb 27 11:50:54 2024 -0800 fix(docs): Make clear the matrix transform example is incomplete commit 7a51a46 Author: Cem Aksoylar <[email protected]> Date: Tue Feb 27 11:41:46 2024 -0800 feat(docs): Add pointer to shields folder in new shield docs commit 849eca7 Author: Xudong Zheng <[email protected]> Date: Fri Feb 23 16:59:48 2024 -0500 refactor(underglow): fix uninitialized variable warning
