1.1 Introduction
The AWR2944EVM is an easy-to-use evaluation board for the AWR294x mmWave sensing device, with direct
connectivity to the DCA1000 EVM.This EVM kit contains everything needed to start developing software for
the on-chip C66x DSP, ARM® Cortex®-R5F controller, and hardware accelerator (HWA 2.0). 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
• On-board antenna
• XDS110 based JTAG emulation with Serial port for onboard 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
• Dual On-board CAN-FD transceiver
• One button and LED for basic user interface
• 12V power jack to power the board
1.3 What’s Included
1.3.1 Kit Contents
• AWR2944EVM
• 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 AWR2944EVM: SDI65-12-U-P5.
1.3.2 mmWave Out-of-Box (OOB) Demo
TI provides sample demo codes to easily get started with the AWR2944 evaluation module (EVM) and to
experience the functionality of the AWR2944 radar sensor. For details on getting started with these demos, see
