Overview

Our Trellis Feather acrylic enclosures are such dense little packages that we put together this guide to help with assembly.

These are sold as both a case+hardware kit (bring your own Trellis, Feather and STEMMA cable), or a more complete kit with Feather M4 and additional parts.

Other tools and skills required:

  • Cutting and stripping wires
  • Soldering
  • Small Phillips head screwdriver

Two Ways to Build

One way to build this Trellis kit is as a “tethered” device — it operates only when a USB cable is plugged in. This is how the Feather M4 Kit Pack is sold.

Another option is as a wireless, battery-operated device. This requires the addition of a panel-mount switch and a lithium-polymer battery, not included in the standard kit. This also implies using a wireless-capable Feather board…most likely one with Bluetooth support (such as nRF52 or ESP32) to create a wireless keypad for a desktop or laptop computer. But, as an open-source device, there’s nothing discouraging you from creating unique wireless projects, if you want to make some kind of WiFi or LoRa remote trigger.

Tips when using the case-only kit (building your own project):

  • This 4-pin STEMMA cable simplifies soldering, and provides just enough extra wire to complete the project. (Included with M4 kit packs.)
  • Use a Feather board without headers installed.
