Hello, I measure the output differential voltage of the drivers (with 100ohm termination resistor) and it is always higher than 0.4V that is referred to the datasheet. What I measure is about 0.68V. Is that normal? Thank you in advance

Hello, I've just received the STM32L475 Discovery kit IoT node. I connected the board through USB cable to my laptop (the JP4 jumper is connected to 5V_ST_LINK) and the power supply LED (LD5) is blinking. Also the board is not visible from laptop (I ...

Hello and thanks for the answers! The chip is supplied with 3.3V and I measure on a termination resistor of 100Ohm as in picture 3 of the datasheet, what I don't use is the two capacitors.

Hi, thank you for your answer. The problem seems to be the power supply, that's why the board is not visible. The power supply LED should be on and not blinking.
