2.2 ATA8350 Demo Kit – Variant B
This Demo and Evaluation kit variant uses an ATSAMC21-XPRO board for the Verifier node and up to five ATAUWB- EK1 boards for the Prover node with an embedded SAMC21 MCU board to control the operation of the ATA8350 UWB device. The following components are used for the Verifier and Prover nodes:
Verifier Node:
- One ATSAMC21-XPRO board
- One ATOLED1 Xplained Pro Extension board
- One ATA8350 Xplained Pro Extension board with ATA8350 UWB device
- One UWB antenna with SMA connector
- One USB cable for 5V USB supply and for connection to a PC with Microchip Studio 7
Prover Node:
- Up to 5 ATAUWB-EK1 boards
with:
- SAMC21 MCU
- ATA8350 UWB module. For more details, refer to the ATA8350 UWB Module Application Note.
- CAN and LIN driver IC
- 12V supply with DC/DC converter for 5V, 3.3V and 1.25V supply
- USB connector for 5V supply
- MCP2221A USB COM port driver with 5V USB supplyNote: The ATAUWB-EK1 board requires an SWD debugger (Microchip-ICE) for programming and debugging of the software application.
- Up to 5 UWB antenna with SMA connector
Each node is programmed with a demo application for the operation as a verifier in VRo mode or as a prover in PRo mode. For more details, refer to the ATA8350 Impulse-Radio Ultra-Wideband (IR-UWB) Transceiver User´s Guide. During the distance measurement, the applications operate at an RF frequency of 6.52 GHz with more than 540 MHz bandwidth. The default frequency range can be changed using the application’s software. With the ATA8350 Evaluation package and ATA8350 Testing packages, the other frequency ranges can be used, for example, 7.04 and 7.56 GHz. For more details, refer to the ATA8350 Impulse-Radio Ultra-Wideband (IR-UWB) Transceiver Data Sheet.
The following figure illustrates the demo setup for the variant B. The Prover and Verifier nodes are preprogrammed with the demo application, and start once the USB power is applied.
