AN54LQ-DB-15

Overview

The Raytac AN54LQ-DB-15 demonstration board is a development board based on the Raytac AN54LQ-15 module. It uses the Nordic Semiconductor nRF54L15 SoC solution. The idea is to connect all the module’s pins to a 2.54mm pin header. It can easily open the verification module functions and connect with other peripheral devices and sensor pins, making it a useful tool for early software development.

Note

You can find more information about the nRF54L15 SoC on the nRF54L15 website [1]. For the nRF54L15 technical documentation and other resources (such as SoC Datasheet), see the nRF54L15 documentation [2] page.

Hardware

The Raytac AN54LQ-DB-15 has two crystal oscillators:

  • High-frequency 32 MHz crystal oscillator (HFXO)

  • Low-frequency 32.768 kHz crystal oscillator (LFXO)

The crystal oscillators can be configured to use either internal or external capacitors.

  • Module Demo Board built by AN54LQ-15

  • Nordic nRF54L15 SoC Solution

  • A recommended 3rd-party module by Nordic Semiconductor.

  • Intended for Bluetooth specification BT6

  • Intended for FCC, IC, CE, Telec (MIC), KC, SRRC, NCC, RCM, WPC

  • 128 MHz ARM® Cortex®-M33 processor with TrustZone® technology

  • 128 MHz RISC-V coprocessor with TrustZone® technology

  • 1.5MB Flash Memory / 256KB RAM

  • RoHS & Reach Compliant.

  • 31 GPIO

  • Chip Antenna

  • Interfaces: SPI, UART, I2C, I2S, PDM, PWM, ADC, and NFC

  • Highly flexible multiprotocol SoC ideally suited for Bluetooth® Low Energy, ANT+, Zigbee, Thread (802.15.4), and Matter ultra low-power wireless applications.

Programming and Debugging

The raytac_an54lq_db_15 board supports the runners and associated west commands listed below.

flash debug

Applications for the raytac_an54lq_db_15/nrf54l15/cpuapp board can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application for more details on building and running.

Note

The raytac_an54lq_db_15 board does not have an on-board J-Link debug IC; Use the Debug out connector of the nRF5340-DK or nRF54L15-DK to connect to the J1 or J9 SWD connector, and use SEGGER J-Link OB IF to debug.

Flashing

As an example, this section shows how to build and flash the Hello World application.

Warning

When programming the device, you might get an error similar to the following message:

ERROR: The operation attempted is unavailable due to readback protection in
ERROR: your device. Please use --recover to unlock the device.

This error occurs when readback protection is enabled. To disable the readback protection, you must recover your device.

Enter the following command to recover the core:

west flash --recover

The --recover command erases the flash memory and then writes a small binary into the recovered flash memory. This binary prevents the readback protection from enabling itself again after a pin reset or power cycle.

Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing.

To build and program the sample to the Raytac AN54LQ-DB-15, complete the following steps:

First, connect the Raytac AN54LQ-DB-15’s J10 connector to you computer using a USB to TTL converter. Then run your favorite terminal program to listen for output.

$ minicom -D <tty_device> -b 115200

Replace <tty_device> with the port where the USB to TTL converter can be found. For example, under Linux, /dev/ttyUSB0.

Next, build the sample by running the following command:

# From the root of the zephyr repository
west build -b raytac_an54lq_db_15/nrf54l15/cpuapp samples/hello_world
west flash
