1 Getting Started
1.1 Introduction
The AWR2544LOPEVM is an easy-to-use evaluation board for the AWR254x mmWave sensing device, with
direct connectivity to the DCA1000 EVM.This EVM kit contains everything needed to start developing software
for the on-chip ARM® Cortex®-R5F controller, and hardware accelerator (HWA 1.5). Also included is on-board
emulation for programming and debugging as well as on-board buttons and LEDs for quick integration of a
simple user interface.
1.2 Key Features
• Speed Wireless Technology 3D waveguide antenna
• XDS110 based JTAG emulation with Serial port for onboard 64-bit QSPI flash programming
• UART to USB Debug port for terminal access using FT4232H
• 60-pin, high-density (HD) connector for external JTAG/ Emulator Interface with TRACE and CSI2 support
• 60-pin, high-density (HD) connector for debug, SPI, I2C and LVDS
• RJ45 connector to stream the captured data over the network to the host PC
• MATEnet Ethernet interface to stream the captured data over the network to an automotive host
• One button and LED for basic user interface
• 12 V power jack to power the board
1.3 What’s Included
1.3.1 Kit Contents
• AWR2544LOPEVM
• 3D waveguide Antenna
• Micro USB cable
• Ethernet Cable
• Mounting brackets, screws, spacers and nuts, to allow placing the PCB vertical
Note
A 12V, > 2.5-A supply brick with a 2.1-mm barrel jack (center positive) is not included. TI recommends
using an external power supply that complies with applicable regional safety standards, such as UL,
CSA, VDE, CCC, PSE, and more. The length of the power cable should be < 3 m.
The following power supply has been tested to work with the AWR2544LOPEVM: SDI65-12-U-P5.
1.3.2 mmWave Out-of-Box (OOB) Demo
TI provides sample demo codes to easily get started with the AWR2544LOP evaluation module (EVM) and to
experience the functionality of the AWR2544LOP radar sensor. For details on getting started with these demos,
see www.ti.com/tool/mmwave-sdk.

2.2 PCB Handling Recommendations
This EVM contains components that can potentially be damaged by electrostatic discharge. Always transport
and store the EVM in the supplied ESD bag when not in use. Handle using an antistatic wristband. Operate on
an antistatic work surface. For more information on proper handling, refer to SSYA010A.

2.3 Power Connections
The AWR2544LOPEVM is powered by the 12-V power jack (>2.5-A current capability). When power is provided
the AR_NRST, VBAT_INT, and 5V0 LEDs glow, indicating that the board is powered up.
Figure 2-4. 12-V Power Connector
Note
After the 12-V power supply is provided to the EVM, TI recommends to press the NRST switch (SW1)
one time to provide for a reliable boot-up state.
2.4 Connectors
2.4.1 MIPI 60-Pin Connector (J19)
This connector provides the standard MIPI 60-pin interface, as shown in Figure 5, for JTAG and trace capability
through emulators such as the XDS560pro. Further information on the emulation and trace header can be found
in the Emulation and Trace Headers Technical Reference Manual.
To use this interface, the JTAG lines from the AWR2544LOPEVM needs to be muxed to MIPI 60-pin connector.
Refer to Section 2.8.1 for more details.
