Page 5: Overview Of The Hp Module Evk
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.
Page 6: Software For The Module Evk
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.

Page 8: Xb112 Breakout Board
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.
Page 10: 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.

Page 19: Pinning/Connectors
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 Table 2.
Page 20 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.

Page 33: Lens Evaluation Kit Lh112
3.3.1 Overview The LH112 lens evaluation kit is an accessory for the XM112/XB112 evaluation kit. The lenses can be used to increase sensor performance. The lenses increase signal strength by focusing the beam width of the radiated EM-waves and thereby concentrating the emitted power. The lens kit is sold separately from XM112 and XB112.
Page 34 HP module EVK hardware user guide – XM112, XB112 LH112 Both lenses can be fitted in the holder in two different positions, D1 or D2. The cover is only used in the D1 position. The two positions will give you slightly different performance. Performance results can be found in the next section.
Page 35: Lens Performance
HP module EVK hardware user guide – XM112, XB112 LH112 3.3.3 Lens Performance The transmitted electromagnetic waves from the Acconeer sensor has different divergence for the E-plane and H-plane. When mounted in front of the sensor the lenses affect the signal strength as well as the spread of the signal.
Page 36: Flashing Of Xm112 Via Usb-Uart Interface
Step 1: The SAM E70 CPU have a ROM boot loader that is used during the software update. In order to enter this boot mode the internal flash must be erased with the following sequence: 1. Connect the XB112 together with XM112 to your PC with a micro USB cable to the “USB1/Power/UART0” connector 2.
