I want to talk to another processor and also use a 4D-display touch display. I need 2 UART ports to do this, but it seems like the photon only has 1 UART port? is this true? do I have to do bit banging for the 2nd serial com?

Number of UART ports on the Photon

Hello,

I am also planning to connect a Sara module to Photon, for which I’ll need Uart2,

as peekay123 said, sparkfun P1 redboard looks a little bit more easier for rework.
