Note: While the adapter was designed for the Teensy 3.1, it is compatible with the Teensy 3.2 as well. The Teensy 3.2 is populated with a more powerful 3.3V voltage regulator with the ability to power additional power-hungry 3.3V devices! Additionally, the adapter interfaces best with the Teensy 3.1, but the Teensy LC can be utilized as well. For more information, check out the specs on PJRC:

The Teensy is a great way to get more computing power than an Arduino, and in less space. When a decently ranged, no-frills wireless serial link is required, the XBee series is a great solution. The Teensy XBee Adapter joins the two with ease and brings wireless to your Teensy projects. This tutorial will demonstrate the basics of using the adapter board.

This tutorial demonstrates:

  • How to initialize Teensy 3.1 HW serial
  • How to initialize Teensy 3.1 SW serial using softwareSerialAlt library
  • The basics of packetizing data.
  • How to make a simple controller that effects something far away

Required Materials

At a minimum, you'll need an XBee explorer, two XBees, a Teensy and the adapter board. Here's a list of things you'll need if you want two Teensy XBee radio stations that are both off-the-grid, plus some useful extras.

Required Tools

You will need a soldering iron, solder, and general soldering accessories. Depending on your setup, you will also need hookup wire, wire strippers, and a hobby knife.

  • Soldering iron and flux core solder
  • Hookup wire
  • Wire strippers
  • X-acto or knife for cutting traces (optional)

Software Requirements
