Resolved! ST4485EB : is it 5V compatible

Hi,The ST4485EB IC mentions that it needs a 3v3 supply. How can we ensure that the A and B lines interoperate with other RS485 devices working at a 5V logic level as the datasheet mentions . Should I just provide 5V supply to this chip so that it int...

Resolved! STUSB4500L Logic Voltage

I am wondering what the logic voltage is for the I/O pins on the STUSB4500L. Under operating conditions they are listed as 0V to 4.5V, but the example circuit shows I2C pullup resistors to 3.3V. Is it safe to connect these I/O pins directly to a 3.3V...

S2-LP DK wrong firmware

Hi,I am trying to use S2-LP DK with a Nucleo + S2-LP Shield. I tried several combinations (4 computers (Windows 10), 6 Nucleo Boards (STML053 and STML152) and 4 S2-LP shields, S2-LP DK V1.2.0, 1.3.0, 1.3.2), I always get the error that I have the wro...
