2 Getting Started

2.1 Introduction

The AWR1443 BoosterPack™ is an easy-to-use evaluation board for the single-chip AWR1443 mmWave

sensing device from TI, with direct connectivity to the TI MCU LaunchPad™ ecosystem. The evaluation

board contains everything needed to start developing on a low-power ARM®-R4F controller. The

evaluation board includes onboard emulation for programming and debugging, onboard buttons, and

LEDs, for quick integration of a simple user interface. The standard 20-pin BoosterPack headers make the

evaluation board compatible with a wide variety of TI MCU LaunchPads and enables easy prototyping.

The AWR1243 BoosterPack is an evaluation board for the AWR1243 mmWave high-performance front

end. The evaluation platform enables raw capture of ADC data from the front end and evaluation of RF

performance.

2.2 Key Features

• 40-pin LaunchPad standard that leverages the LaunchPad ecosystem

• XDS110-based JTAG emulation with serial port, for onboard QSPI flash programming (for AWR1443)

• Backchannel UART through USB to PC, for logging purposes

• Onboard antenna

• 60-pin high density (HD) connector, for raw ADC data over CSI, or the high-speed debug interface

• Onboard CAN transceiver (for AWR1443)

• One button and two LEDs, for user interaction

• 5-V power jack, to power the board

2.3 What is Included

2.3.1 Kit Contents

• AWR1443BOOST or AWR1243BOOST

• Mounting brackets, screws, and nuts, to allow placing the PCB vertical

• Micro USB cable to connect to the PC

NOTE: Not included: 5 V, >2.5-A supply brick with 2.1-mm barrel jack (center positive). TI

recommends using an external power supply that complies with applicable regional safety

standards such as UL, CSA, VDE, CCC, PSE, and so on. The cable length of the power cord

must be < 3 m.

2.3.2 mmWave Proximity Demo

TI provides sample demo codes to easily get started with the AWR1443 evaluation module and

experience the functionality of the AWR1443 mmWave sensor. For details on getting started with these

demos, see the mmWave SDK User Guide.

3.1 Block Diagram

Figure 3. BoosterPack™ Block Diagram

3.2 Connecting BoosterPack™ to LaunchPad™ or MMWAVE-DEVPACK

This BoosterPack can be stacked on top of the Launchpad, or the MMWAVE-DEVPACK, using the two

20-pin connectors. The connectors do not have a key to prevent the misalignment of the pins or reverse

connection. Therefore, ensure reverse mounting does not take place. On the AWR1443 BoosterPack, we

have provided 3V3 marking near pin 1 (see Figure 4). This same marking is provided on compatible

LaunchPads which must aligned before powering up the boards.

3.3 Power Connections

The BoosterPack is powered by the 5-V power jack (>2.5-A current limit). As soon as the power is

provided, the NRST and 5-V LEDs glow, indicating that the board is powered up (see Figure 5).

Figure 5. Power Connector

NOTE: After the 5-V power supply is provided to the EVM, TI recommends pressing the NRST

switch (SW2) once to ensure a reliable boot up state.

3.4 Connectors

3.4.1 20-Pin BoosterPack™ Connectors

The BoosterPack has the standard LaunchPad connectors (J5 and J6) which enable the BoosterPack to

be directly connected to all TI MCU LaunchPads (see Table 1). While connecting the BoosterPack to other

LaunchPads, ensure the pin 1 orientation is correct by matching the 3V3 and 5-V signal marking on the

boards (see Figure 6).

• PGOOD – This signal indicates the state of the onboard VIO supply for the AWR device coming from

the onboard PMIC. A high on the PGOOD signal (3.3 V) indicates that the supply is stable. Because

the IOs are not failsafe, the MCU must ensure that it does not drive any IO signals to the AWR device

before this IO supply is stable. Otherwise, there could be leakage current into the IOs.

• PMIC Enable – This signal goes onboard PMIC enable. The MCU can use this signal to completely

shut down the PMIC and AWR device to save power. The power up of the PMIC takes approximately 5

ms once the Enable signal is released.

NOTE: To enable this feature, the R102 resister must be populated on the EVM.

• ANA1/2/3/4 – These are inputs to the GPADCs (general purpose ADC) available on the AWR1443

device.
