Restrictions apply to this RF Equipment for use in Australia:

Only to be operated on 433Mhz / 915-930Mhz / 2.4Ghz (check the product description for compatible frequency ranges).
If operating outside of shared frequencies or in such a way that is beyond low interference potential devices are intended to function, then you have obtained the appropriate authorisation to do so.

For use in other locations around the world:

Follow region-specific frequency spectrum rules.

A declaration of use will need to be submitted during checkout.

Does your project require high-precision, cutting-edge distance measurement? Or maybe speed, motion, or gesture-sensing? We're not talking about simple ultrasonic or even infrared here, but 60GHz radar! Well say hello to the SparkFun A111 Pulsed Radar Breakout! The A111 is a single-chip solution for pulsed coherent radar (PCR) and comes complete with an integrated antenna and an SPI interface capable of clock speeds of up to 50MHz. Though the A111's primary use case is distance-sensing, it also supports applications in gesture, motion, material, and speed-detection at distances of up to two meters.

SparkFun Pulsed Radar Breakout for the A111 includes a 1.8V regulator, voltage-level translation, and it breaks out all the pins of the pulsed radar sensor to both 0.1-inch and Raspberry Pi-friendly headers. The Pulsed Radar Breakout is designed to sit directly on top of a Raspberry Pi but it doesn't span all 40 (2x20) pins of a Raspberry Pi B (or later), but the 26-pin -- 2x13 -- header should be compatible with any Pi.

Acconeer has developed a visualization tool written in Python that demonstrates data collection in real time. It's called the Acconeer Exploration Tool and is an incredible resource when first starting out with the A111 Pulsed Radar. As an example it will graph distance or presence sensing, giving you a count of the number of sweeps, which communication port (SPI or I²C) data is being sent through, and much much more. The tool supports both Windows and Linux and requires Python version 3.6 or later. This tool is available through their GitHub Repository, go on over a take a look!

Heads up! The A111 was designed to work with an ARMv7 to work at a minimum. Sparkfun were able to get the sensor working on the Raspberry Pi 3, 3B , and 4.
