So far, how-to documentation states that Acconeer Exploration Tool is to be used with Acconeer Devkits. Is it possible to use the tool with the SparkFun Pulsed Radar Breakout ? SparkFun Pulsed Radar Breakout is able to obtain multiple target information as the Acconeer devkits state? Thank you very much for your attention.</p>

Most issues were related to the SDK revisions breaking the examples (when this product first released); however, Acconeer (sensor manufacturer) has since resolved that problem.</p></p>

But the SparkFun RedBoard Artemis Nano has a Cortex M4 with ARMv7E-M, so as long as the correct pins are connected it should work?</p>

This appears to be the package data sheet. There's a reference to Antenna-in-Package (AiP), and the pinout has nothing about driving an RF output, so I'd guess you're limited to the antenna in the chip itself.<p>According to the linked data sheet, the unit has a "HPBW of 80 (H-plane) and 40 degrees (E-plane)", which as far as I can tell from the wikipedia <a href="https://en.wikipedia.org/wiki/E-plane_and_H-plane" rel="nofollow">article</a> means that in one of the two axes the signal is projected along, you can get down to 40-ish degrees beam angle. You might be able to scan with a servo or something like people do with cheap sonar sensors. You might even be able to figure out the width of the object by measuring when the edges of the beam start to register the same object scanning from opposite directions. I guess it really depends on how "crisp" the edge of the beam is.</p></p>

"the A111's primary use case is distance-sensing", but isn't that the same as just "use"? Make us oldsters happy and hyphenate the darn thing! I come to a halt every time I see that I need to 'use a case' where it doesn't apply.</p>

Second: What is the antenna beam shape?
In addition: I would like to have an ability to switch to other antennas. That would allow me to make it directional or a simple scanned array.
Thanks</p>
