Functional Description

Sub-GHz Modem

• The devices features a combined DASH7-FSK/LoRa & LoRaWAN modem functioning @868 MHz in the RED/EU regulated areas and @915MHz in the FCC regulated areas. It both allows communication over long-range LoRaWAN and mid-range DASH7-FSK/LoRa, and over-the-air configuration and code update using the D7A protocol.

UM-1 combo UWB/BLE/NFC

• The UM-1 Module is a full-function RTLS / wireless modem subsystem in a compact factor, composed of Qorvo DWM1001 hardware, and WizziLab proprietary firmware. The UM-1 module enables customers to quickly get a RTLS system up-and-running, also provides additional over-theair communication capabilities through the UWB, BLE and NFC interfaces. The UWB part of the system is designed to operate on 4.493 GHz (IEEE 802.15.4- 2011, Channel 3) and 6.490 GHz (IEEE 802.15.4- 2011, Channel 5) Nominal Centre Frequencies with a 500 MHz Bandwidth and data rates of 110 kbps and 850 kbps. It also features a BLE modem and a passive NFC-A listening device.
• The UM-1 module comes loaded with embedded firmware which provides two-way ranging (TWR) and BLE (tap-to-connect, beaconing and sniffing in Eddystone and IBeacon format) functions. The firmware is available as a nonmodifiable library, which provides a function API. This allows to execution the host firmware directly on the MCU of the UM-1.

UWB transceiver

• The UM-1 module has a DW1000 UWB transceiver mounted on the PCB. The DW1000 uses a 38.4

• MHz reference crystal. The crystal has been trimmed in production to reduce the initial frequency
  error to approximately 3 ppm, using the DW1000 IC’s internal on-chip crystal trimming circuit.

• Always-On (AON) memory can be used to retain DW1000 configuration data during the lowest power operational states when the on-chip voltage regulators are disabled. This data is uploaded and downloaded automatically. The use of DW1000 AON memory is configurable.

• The on-chip voltage and temperature monitors allow the host to read the voltage on the VDDAON pin and the internal die temperature information from the DW1000.

• See the DW1000 Datasheet [2] for more detailed information on device functionality, electrical

• specifications and typical performance.

Bluetooth® Microprocessor Nordic nRF52832

• The nRF52832 is an ultra-low power 2.4 GHz wireless system on chip (SoC) integrating the nRF52 Series 2.4 GHz transceiver and an ARM Cortex-M4 CPU with 512kB flash memory and 64kB RAM.
• See the nRF52832 datasheet [1] for more detailed information on device functionality, electrical specifications and typical performance.

NFC Passive Tag

• Allows identification & configuration over NFC

Three Axis Motion Detector

• The LIS2DH12 is an ultra-low-power high-performance three-axis linear accelerometer with digital I2C/SPI serial interface standard output. The LIS2DH12 has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz. The self-test capability allows the user to check the functionality of the sensor in the final application. The device may be configured to generate interrupt signals by detecting two independent inertial wake-up/free-fall events as well as by the position of the device itself.
• The LIS2DH12 is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
• See the LIS2DH12TR Datasheet [4] for more detailed information on device functionality, electrical specifications and typical performance.

• Depending on battery capacity, the application is configured in one of the following operation modes :
• Static tag – performs location on transition from motion to stable.
• Static tag with pick-to-light – performs location on transition from motion to stable. Turn on LED pattern up to 12 times a day.
• Dynamic tag – performs location continuously during motion.
• Anchor – location reference
• Refer to the lifetime limitations in the Hardware Section.
