1. Overview of the XE123/124 Entry+ Module
Evaluation Kit
1.1. Introduction
The XE123/124 Entry+ Module Evaluation Kit (The EVK) is a development platform targeting
straight-forward use cases where small size, low cost and low power is key.
The EVK features Acconeer’s XM123 or XM124 Entry+ module, including the A111 radar sensor.
The A111 radar sensor is an optimized low-power, high-precision 60 GHz radar with antenna in
package (AiP) and integrated baseband. Together with the ARM® Cortex®-M4 STM32L431 MCU,
the XM123/124 Entry module becomes a cost- and size-optimized low-power radar sensor.
The A111 is based on pulsed coherent radar technology (PCR). It has leading-edge patented sensor
technology 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 2 m with a continuous
sweep update frequency of up to 600 Hz. With the use of a dielectric lens the range can be
significantly longer.
The A111, 60 GHz radar is not compromised by natural sources of interference such as noise, dust,
color, direct or indirect light.
The EVK consists of:
1 XE123/124 Evaluation board with an XM123 or XM124 Entry module soldered onto it.
The XE123/124 is compatible with Acconeer LH132 lens kit (LH132 is also compatible with
evaluation kit XE132). LH132 is sold separately.

2. Software for the EVK
2.1. SW download
The SW is available for download at https://developer.acconeer.com. Here you will find both a
Software Development Kit and a Module Server version. SW User Guides can be downloaded at the
same site.
2.2. SW API Description
The Acconeer SW comes with an API (Application Programming Interface). Acconeer provides
several service-oriented example and reference applications, as well as customer guidelines for
application development when utilizing the API. All APIs provided by Acconeer are documented.
Unzip the SW zip file downloaded from Acconeer’s download site. In the file structure, please locate
/doc folder from where API documentation in HTML format is found at doc/html/index.html.

3.1. XE123/124 Evaluation Board
3.1.1. Overview
The XE123/124 is an evaluation board including the XM123 or XM124 Entry+ module. It makes the
interfaces from the XM123/124 module accessible for evaluation and debug. It also enables flashing
of the XM123/124 via USB-UART or SW-DP. The XM123/124 Entry module is included in the
XE123/124 Evaluation board. In Picture 1 and Picture 2 you will find the XE123 and XE124 front
sides where the XM123 and XM124 is mounted. Picture 3 shows the back side of XE123/XE124.
