LC13 and LC14 Specifications

Overview

This section provides technical details of the LC13 and LC14 devices. The LC13/LC14 devices can be used to create an Anchor Node (AN), Anchor Initiator Node (ANI), Tag Node (TN) and Gateway for a Real-Time Location System (RTLS). It is also compatible with FiRa Nearby Interaction and Two-Way Ranging Angle-of-Arrival (TWR-AoA) demo. Furthermore, this open platform can be used for developing UWB or Bluetooth applications.

Key Features

  • Based on Murata 2AB SIP (MCU nRF52840 with Bluetooth, UWB QM33120W IC, LIS2DW accelerometer, crystals and internal power regulators).

  • Qorvo QM33120W - Ultra Wideband (UWB):

    • Based on the IEEE802.15.4z standard and implements enhanced security features.

    • Supports both channel 5 (6.5 GHz) and channel 9 (8 GHz) with UWB RF compliance compatible with FCC, Japan’s ARIB, ETSI and +10dB ETSI of the CE.

    • Integrates Low Noise Amplifier (LNA) and Power Amplifier (PA) to increase the UWB range (up to 150m).

    • With integrated non-AoA (LC14) and AoA antennas (LC13).

    • FiRa™ PHY and MAC compatible. Interoperable with the Apple U1 chip and Android FiRa compatible smart devices.

    • Backward compatibility with DW1000 IEEE802.15.4a UWB IC on channel 5.

  • Supports Two-Way Ranging (TWR), Time Difference of Arrival (TDoA) and Phase Difference of Arrival (PDoA).

  • Nordic Semiconductor nRF52840 - Bluetooth® Low-Energy (BLE) 5.3 RF Technology with an integrated antenna.

  • Supports NFC tag antenna connector.

  • 2 USB C ports integrate a DAPLink programmer with Virtual COM and a USB device interface for data communication.

  • Alternatively, J-Link can be used via an onboard 6-pin Tag Connect compatible connector.

  • It contains RGB LEDs, 2x GREEN LEDs, a front button, two side buttons, a USB connector for a nRF52 USB device, a buzzer, a haptic motor and extra GPIOs for connection with external sensors or IOs.

Note

Please kindly refer to the Murata 2AB module and Qorvo DW3000 IC pages for additional details.

Software Compatibility

It is compatible with LEAPS UWBS, Qorvo FiRa compatible UWBS (Nearby Interaction, TWR AoA), PANS PRO UWBS and third-party stack (open platform). The default firmware is LEAPS UWBS with Qorvo FiRa compatible demos supplied from the production.

Note

  • To achieve the lowest power consumption, please cut the SWD_DIO jumper. The sleep current would be around 24uA @ 3.7V. When not cut, the sleep current would be around 270uA @ 3.7V.

  • To be able to use the external Jlink, please cut the SWD_DIO jumper.

  • The other jumpers can stay untouched.

Safety Instructions

  • Do not expose the device to water or moisture whilst in operation.

  • Do not expose the device to heat from any source.

  • Take care whilst handling to avoid mechanical or electrical damage to the product.

Warnings

  • This device should only be connected to an external power supply rated at 5V/0.5A DC or a 3.7V battery.

  • Replacement of a battery with an incorrect type can defeat a safeguard (for example, in the case of some lithium battery types).

  • Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery, which can result in an explosion.

  • Leaving a battery in an extremely high temperature surrounding environment can result in an explosion or the leakage of flammable liquid or gas.

  • A battery subjected to extremely low air pressure may result in an explosion or the leakage of flammable liquid or gas.

Important Notice

  • The hardware and software of the kit are intended for demonstration purposes only. To obtain an industrial-grade system, please kindly contact us to discuss the specific needs and requirements.

  • For more detailed information on Qorvo software tools, such as Qorvo’s FiRa compatible stack, Qorvo Nearby Interaction and UWB Ranging & AoA Demo Application, please refer to the appropriate documentation or resources that are available at Qorvo’s website.
