1 Overview of the HP module EVK.
1.1 Introduction
The HP Module Evaluation Kit (The EVK) is a platform for evaluating the HP Module. The module is
based on the Acconeer A111 sensor, which is an optimized low-power, high-precision 60 GHz radar
in one package solution with integrated Baseband, RF front-end and Antenna. In the HP Module The
A111 sensor is integrated together with an M7 processor (Atmel SAME70) which facilitates signal
processing for advanced use cases. For an introduction to Acconeer’s technology and product offer
refer to “Introduction to Acconeer’s sensor technology”, available at the Acconeer website.
The EVK consists of
 One HP Module featuring A111 and an Atmel SAME70 MCU. The module is not pre-flashed and
an XB112 is needed to easily flash it.
 One XB112 breakout board which enables connection to external devices.
 LH112

2 Software for the Module EVK
2.1 Software download
All software is available for download at https://www.acconeer.com/products, more details about the
software offer and structure can be found in the document “Introduction to Acconeer’s sensor
technology”, available at the Acconeer website.
For the HP Module Acconeer provides two deliveries, a software development kit (SDK) for ATMEL
SAME70 and a module software image for XM112. Details about the software offer can be found in
the document “Introduction to Acconeer’s sensor technology”, available at the Acconeer website.
2.2 Module software for XM112
The HP Module software enable register-based access to radar functionality from external devices
connected to the HP Module. The module software is delivered as an image.
Typical usages of the HP Module software are:
1. Integration of radar functionality in your product to decrease development cost and time to
market.
2. Module evaluation and algorithm development in Python together with the “Acconeer Python
Exploration Tool” that is available for download on GitHub. https://github.com/acconeer/
The HP Module software provides a rich register-based API that can be accessed over UART, SPI and
I2C1.
The Module software will initially support the following services and detectors:
- Power Bin Service
- Envelope Service
- IQ Data Service
- Distance peak detector with fixed threshold
Support for more detectors is planned for future module software releases.
2.3 SDK for ATMEL SAME70
For users that wish to use the module MCU to implement their own applications and other SW
components we also provide an SDK.
The Acconeer SDK comes with an API (Application Programming Interface). Acconeer provides
several service oriented example applications, as well as customer guidelines for application
development when utilizing the API. All APIs provided by Acconeer are documented in the SDK.
1 The I2C support is planned but is not available at the time of writing.

3.1 XB112 Breakout Board
The XB112 is Acconeer’s breakout board and part of the Module EVK.
3.1.1 Overview
The XB112 is a breakout-board designed for the XM112 Radar Module. It makes the interfaces from
the XM112 radar module accessible for evaluation and debug. It also enables flashing of the XM112
via USB-UART or SWD. The XM112 is connected to the XB112 via a board-to-board connector on
the top side of the PCB. Below you will find pictures of both front and back side of the breakout
board.
Picture 1 shows the XB112 connector board, front side.

3.1.2 Power
The EVK is powered via the USB connectors on XB112. USB1 powers the USB-UART chip (U4) and
the XM112. USB2 powers the USB-SPI chip (U5). If no SPI data is needed, the USB2 can be left
unconnected. USB1 must however always be connected. If the USB-UART interface is not used, a
dedicated USB charger can be inserted to USB1.
When the power LED on the XB112 is lit, the breakout board and the XM112 radar module (if
connected to the board-to-board connector on the top side of XB112) are powered on and ready for
use. For details regarding the power management on XB112, refer to the XB112 product brief.

3.1.6 Pinning/Connectors
3.1.6.1 USB1 (J1)
USB1 is used as power supply for the XB112 and the XM112. It is also used for flashing and
communicating over UART. USB1 is connected to the FTDI chip FT230XS which converts the
UART interface from XM112 into USB signals. The pinout of USB1 is shown in
.

3.1.6.3 2x20 pin header (J3)
The 2x20 pin header (1.27mm pitch) is not mounted. The reason is that it is intended for Acconeer
internal use only. All the interfaces available in the 2x20 pin header are also available in the other
connectors. The pinout of the 2x20 pin header is shown in Table 4.
