2025-07-06 I have added an updated firmware version to support online layout configuration with https://zmk.studio/ The firmware is configured to add up to 10 more layers to the keyboard (15 of them in total.) Changes made in that app/page are applied instantly. When ZMK.Studio asks to unlock the keyboard - press Tab+B (as in my original layout.) For v5, v8, v8b, and v11: thumbsupv5qs-nice_nano_v2-zmk-studio-touchpad.uf2 For v9: thumbsupv9qs-nice_nano_v2-zmk-studio-touchpad.uf2 Location: https://www.dropbox.com/scl/fo/2s8vz5tq5lffmpjuqbz2c/h?rlkey=71amow1mhhwfe54c0ywx59bfc&st=cs2i6x7z&dl=0 To flash the file - press twice the reset button on back of the middle board. There should be a new drive added temporarily to your system. Copy that file into this drive, keyboard will restart. This firmware supports the touchpad, if installed.
User manuals and related materials for ThumbsUp! keyboards I sell on Etsy and eBay.
