Overview
Device supported
This document supports the AW-HM662 (18 x 24 mm LGA Module). The AW-HM662 test board can be operated in Host Mode or Standalone Mode. You can use Newracom Modem Test Tool for RF performance testing.
Basic Setup and Requirements for Host Mode RF Verification
This section provides detailed information about the settings for the AW-HM662 demo board. The overview of the AW-HM662 demo physical photo and PCB placement (TOP). The description of jumpers’ functions and settings on the demo board is as follows:
Operation Mode Configurations
AW-HM662 can be operated in Host Mode or Standalone Mode through the setting of jumper J506
Mode = H (Standalone Mode switch J506 to 1-2)
Power Supply
- The 5.0V power supply can be provided by a USB Type-C connector (CON301) and short J301.
- The 4.0V power supply (short J304 pin.1 and pin.2) for AW-HM662 pin.5 VDD_FEM is converted from the 5.0V power supply through the LDO on the demo board. You can measure the current of VDD_FEM by connecting an ammeter in series with J510.
- The 3.3V power supply (J508) for AW-HM662 pin.6 VBAT is converted from the 5V power supply through the LDO on the demo board. You can measure the current of VBAT by connecting an
ammeter in series with J508. - The 3.3V power supply (short J305 pin.2 and pin.3) for VDDIO of AW-HM662 pin.51 is converted from the 5.0V power supply through the LDO on the demo. You can measure the current of VDDIO by connecting an ammeter in series with J509.
USB to UART (J201)
The USB to UART Bridge IC used in this demo board is FT232RNL. Please download and install the FT232RNL driver from the FTDI official website before use. Set the UART port (UART0) of AW-HM661 by short-circuiting J201 pin 5 to pin 6 and pin 7 to pin 8.
Modern Test Tool Usage
Modem Test Tool is a GUI tool for performing RF/PHY-level TRX tests on NRC7394 modules with a logging functionality. You can measure the RF performance of the frequency, bandwidth, MCS, etc You want to measure through the setting of configurable parameters.
AW-HM662 Demo Board Offers Communication Interface to An External Host.
The 5.0V power supply can be provided by Raspberry Pi4 through connector J401 and short J301 and J302. AW-HM662 can be connected to the Host side via SPI interface. The picture below is a photo of AW HM662 demo board connected to Raspberry Pi4 via J401. Please note that the mode of J506, must be set correctly when operating in Host Mode.
Standalone Mode Operation
This section provides detailed information on how to use AT commands to transmit and receive packets.
Download Standalone AT-CMD Firmware
Set the AW-HM662 demo board to download mode (switch J506 to 2-3). Connect the demo board to the PC using a USB cable, and then execute the Newracom Firmware Flash Tool.
XIP BOOTLOADER PATH
Select nrc7394_standalone_xip_ATCMD_UART.bin and then press START to download the firmware.
AT Command Application
Set the AW-HM662 demo board to standalone mode (switch J506 to 1-2), and use DuPont cable to connect J201 pin.5 to J502 pin.17, and connect J201 pin.7 to J502 pin.25. Then use a USB cable to connect the demo board to the PC, and the user can execute AT commands through UART1.
Connect J201 pin.5 to J502 pin.17, and connect J201 pin.7 to J502 pin.25
Use the Newracom AT-CMD Test Tool to execute AT command instructions.
FAQs
Q: Can the AW-HM662 module be used in both Host Mode and Standalone Mode?
A: Yes, the AW-HM662 module can be operated in both Host Mode and Standalone Mode by configuring the jumper settings accordingly.
