1.3.1 Data Connection via USB Cable (USB Mode)
- Connect a USB cable (micro B to type A), A LED will light up to show that the board is powered and working
- 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.
Please see Evalkits r4 Software/Firmware section to find detailed information about how to connect EvalKit (WebGUI or terminal program). If you want to proceed with WebGUI, you can consider WebGUI section or if you want to continue with a terminal program you can follow Terminal.
1.3.2 Mounting the Lens (Optional)
Please see lens datasheet [25] for more information.
