    How much is Edison's TTL level? And for Arduino and Mini breakout.


      1. Recently, I want to use Edison (mini breakout)  to read serial data from STM32 (3V3 ttl level), can I directly connect the TX and RX from STM32 to my Edison?


      2. Furthermore, I have tried to directy connect the STM32 to Edison for Arduino expansion, but i cannot received  any data. I think the parameter was correct,   Band rate was 115200. Here is my connection:



      STM32    RX<--------->TX      Edison for Arduino      



      3. So I guess maybe that's related to TTL level.


      Pls help,


      Many thanks.
