Wizfi communication

Hello,

  1. If I want to connect an MCU with Wizfi250 via SPI, should I use 3.3v voltage regulator or the pin are 5v tolerant?

  2. In case of UART connection and I want to use RTC/CTS, are those as well 3.3v?

Thank you,

Best Regards,

Andreas Achilleos

Hi Andreas Achilleos.

As you know, In all situations that were considered, you have to use 3.3v.

Thanks.
