1. Overview of the XC111-XR111 Evaluation Kit
1.1 Introduction
The XC111-XR111 Evaluation Kit (The EVK) is a development platform featuring Acconeer’s A111.
This is an optimized low-power, high-precision 60 GHz radar in one package solution with integrated
Baseband, RF front-end and Antenna.
The A111 is based on pulsed coherent radar technology (PCR). It has leading-edge patented sensor
technology and with pico-second time resolution. The A111 sets a new benchmark as far as power
consumption and distance accuracy are concerned and it comes fully integrated in a small package of
29 mm2.
The A111 can measure absolute distance with mm accuracy up to a range of 2m with a continuous
sweep update frequency of up to 1500 Hz.
The A111, 60 GHz radar is not compromised by any natural source of interference such as noise, dust,
color, direct or indirect light.
The EVK consists of
1 XC111 Connector board with the possibility to connect up to 4 Radar sensor boards.
1 XR111 Which is Acconeer’s sensor board featuring A111.
The EVK does not contain any processor or micro controller. It was designed for use with a Raspberry
Pi 3.
1.2 Getting Started
A Quick Installation Guide is available at https://youtu.be/sj9Rxb7WshI
This short instruction video will ensure a smooth setup and installation. For more information on
retrieving the Acconeer SW, please refer to the next chapter.

4 Design considerations
The EVK was designed for sensor evaluation purposes only. Should you want to design a product, it is
strongly recommended to carefully read and follow the A111 data sheet. The Evaluation Kit is not
optimized for product development.
