1 Requirements

1.1 SiRad Easy®

Easy with lens.jpg
  • Microsoft Windows 10
  • GUI by Silicon Radar from [1]
  • USB cable mini to type A

1.2 SiRad Simple®

  • Microsoft Windows 10
  • GUI by Silicon Radar from [2]
  • Serial-FTDI to USB cable or adapter

2 Hardware

  • TRX_024_006 SiRad front end datasheet [4]
  • TRA_120_002 SiRad front end datasheet [5]
  • TRX_120_001 SiRad front end datasheet [6]

2.1 Changing the Radar Front End

The SiRad Easy® Evaluation Kit consists of two radar front ends (24 GHz and 122 GHz), an evaluation baseband board, and an ST Microelectronics Nucleo64 microcontroller board that is stackable. Silicon Radar delivers the Evaluation Kit in the 122 GHz configuration without the lens assembled. Follow the instructions below for changing the Evaluation Kit configuration in SiRad Easy® User Guide.

2.2 Data Connection

Please see User Guide SiRad Simple® User Guide and SiRad Easy® User Guide to set up data connection via USB Cable/External Header/Wifi. For more information and additional documents please see Customer Download Area.

  • In some cases, the ST-LINK USB Driver may not work, if an additional COM port number cannot be seen in the device manager after the Evaluation Kit has connected, installing a different Virtual COM Port Driver, which is mentioned in the requirements, could be the solution.
  • WiFi only: If you are using a WiFi connection to connect to the Evaluation Kit, unfold the ‘COM’ section in the control panel on the left side of the WebGUI. Provide the IP address and the port of the WiFi module of the SiRad Easy® you want to connect to before you proceed, like so: ‘’. The standard port is 9090. Click the ‘Connect’ button on the top left to connect to the WebSocket provided by the COM2WebSocket tool or to the WiFi module of the Evaluation Kit. The WebGUI should display the sensor data.

Please see Evalkits #Software section to find detailed information about how to connect EvalKit ( Silicon Radar WebGUI or terminal program). If you want to proceed with Silicon Radar WebGUI, you can consider WebGUI section or if you want to continue with a terminal program you can follow Terminal.

2.3 Mounting the Lens (Optional)

Please see lens datasheet [7] for SiRad Easy® and SiRad Simple® for more information.
