Product Overview
The Qorvo® QM33120WDK1 is a development kit for the low
power low cost QM33110W and QM33120W UWB transceivers.
This kit can be used to evaluate the hardware performance of
the devices in TWR, TDoA and AoA systems and can help to
build an evaluation real time location system (RTLS).
It also enables the development of applications based on
DW3110, DW3120, DW3210, DW3220 UWB transceivers.
It includes two different daughter boards (AoA and non-AoA)
mounted on two Nordic nRF52840 DK evaluation boards.
Application firmware development is facilitated by the features
of the Nordic boards such as on-board J-Link debugger, USB
and Bluetooth® Low Energy interfaces.
The QM33120WDK1 is designed to develop applications
compatible with PHY and MAC FiRa specifications.

Table 1 : Kit Content
Note that none of these parts can be ordered separately. They will only be sold as kits.
QM331x0WEVB board and nRF52840 DK board are shipped connected.
Screw the antennas on each QM331x0WEVB board paying attention to the antenna orientation. It is recommended to use a 1 N*m
torque wrench to attach the antenna to the QM331x0WEVB boards, for example HUBER+SUHNER 74_Z-0-0-21.
Attach the nRF52840 DK boards to their plastic stands using the included standoff.
Connect both nRF52840 boards to a PC using the included USB cable and refer to the section QorvoOne GUI.

2 Nordic nRF52840 DK configuration
Figure 2 : nRF52840 DK configuration
J-LINK OB (On-Board Debug Probe) is an integrated programming and debugging tool and should be connected to the Host used to
program or debug the nRF52840 firmware with Segger J-Link and Segger Embedded Studio software.
Figure 3 : J-Link OB
For normal operation, the Host should be connected to nRF52840 SOC through the nRF52840 USB connector.

7 QorvoOne GUI
The nRF52840 DK boards are shipped preprogrammed. So, you can connect the two nRF52840 DK boards to the PC using the supplied
USB cable. Make sure that the antennas face each other during the evaluation.
Figure 5 : AoA System Evaluation Setup
Install QorvoOne GUI software included in QM33_QorvoOne_DK package and start the application.
The boards will be detected and displayed on the main screen.
For AoA evaluation, ensure that the QM33120WEVB (the one with the dual antenna) is configured as initiator.
Refer to the QM33120WDK1 Quick Start Guide for further information.
