Hello. I'm designing a rigid flex cable and the ground plane hatch spacing seems to be dependent on the min rise/fall time of the signals. Does anyone know what that might be on a 5MHz VOXL2 SPI bus?

USB to TTL cable connectionI'm trying to connect the VOXL2 to a USB using a TTL to USB serial converter like this:

I was planning on using J3 pins 27 & 29 as RX & TX. Do you know what pins would work for the "Clear to send control input/ handshake signal" and the "Request to send control output/ handshake signal"? Would any GPIO pin be acceptable?
