Introduction

Does your project require high-precision, cutting-edge distance, speed, motion, and/or gesture sensing? We're not talking ultrasonic, or even infrared here, but 60GHz radar! Say hello to our tiny, pulsed radar friend the Acconeer A111!

The A111 is a single-chip solution for pulsed coherent radar (PCR) -- it comes complete with antennae and an SPI interface capable of speeds of up to 50MHz. Applications for PCR include distance-sensing, gesture, motion, and speed detection. The sensor can monitor one-or-more objects at distances of up to two meters.

Our breakout board for the A111 includes a 1.8V regulator, voltage-level translation, and it breaks out all pins of the pulsed radar sensor to both 0.1-inch and Raspberry Pi-friendly headers.

Required Materials

To use the A111 you'll need either an ARMv7 or an ARM Cortex-M4 -- the closed-source SDK currently only supports these architectures. This tutorial will explain how to use the radar sensor with a Raspberry Pi -- a platform based on an architecture supported by the A111's SDK.

The A111 Breakout includes a 20-pin, 2x10 female header, which should mate to Raspberry Pi's of any generation. If you'd rather manually wire the A111 to your Raspberry Pi, male headers and about 9 male-to-female wires should do the trick.
