NEW GUIDE: John Park’s Launch Deck Trellis M4 @adafruit @johnedgarpark #adafruit

Check out the new Launch Deck Trellis M4 guide in the Learn System!

The general purpose computer coupled with the general purpose keyboard and mouse is a powerful combination, but wouldn’t you like something a bit more… specific purpose for launch applications, playing media, and firing off keyboard-combos? Enter the Launch Deck Trellis M4!

The Trellis M4 can emulate a USB keyboard, so your computer has no idea that when you press a single button on the Trellis M4 it isn’t actually you pressing a four button keyboard combo on your real keyboard! It’s a bit like a totally customizable, CircuitPython powered, Open Source Streamdeck!

The Launch Deck Trellis M4 uses a simple CircuitPython program to send totally customized HID USB keycode and media commands with any of its colorful 32 buttons. You can decide which buttons do what, and color code them as you like. A red button to launch Gmail, an orange button for Firefox, a green button for an old school homebrew themed terminal window, and so on.

This guide will show you how to set up the NeoTrellis M4 to send keyboard combos out to an app launching program, such as Automator and Quicksilver on macOS, and AutoHotkey in Windows.
