Freakduino Standard

The Freakduino is the classic wireless Arduino-compatible board by FreakLabs designed for people that simply want to transmit data wirelessly. It pairs the ease-of-use of the Arduino environment with lightweight wireless software that simply works so that people could send and receive wireless sensor data quickly and easily.

Since its initial introduction almost ten years ago, thousands of Freakduinos have been sold, powering applications in environmental monitoring, precision agriculture, garden monitoring, home safety, and scientific research. We’re also able to offer the design in multiple frequencies to suit your needs. Whether you need the international compatibility of 2.4 GHz or the increased range of 900 MHz, or even long range versions of both, we’ve got you covered. We also offer multiple antenna configurations to suit your range requirements.

Currently on its third revision, this version of the Freakduino improves on the previous designs by reducing power for longer battery life, integrating power circuitry that allows it to be battery operated, and still reducing the cost. Previously, the battery power circuitry was sold separately as an add-on, but due to manufacturing improvements, we are proud to offer it as part of the complete device, free of charge. We’ve wanted to do this for a long time since it’s the most popular add-on for the design, and changes it from a device that must be tethered to a power source, to one that can operate standalone, anywhere in the world. On top of this, the power reduction also allows it to last up to six months on two AA batteries in its lowest power mode.

The Freakduino differs from other wireless devices by being designed as a complete standalone device. There are other devices that are designed to be integrated into larger designs, but the Freakduino is a complete Arduino system with wireless communications, battery conditioning circuitry, low power optimizations, and is compatible with the complete array of third party Arduino shields and libraries available. It also comes with an optional ruggedized enclosure or bottom mounted battery case and legs. All the hard design work has already been done so you can focus on your application.

The Freakduino has been used by organizations such as the World Bank, UNESCO, International Atomic Energy Agency, MIT Media Lab, and many more, but most importantly, it’s designed for people that value environmental monitoring, quantitative data, open source and DIY culture, and citizen science. Along with all that, there’s a no-questions-asked full refund if you’re not satisfied with your purchase.
