Tool/software:
Hi, I need to connect two PCBs over SPI using wires, which can be as long as 3 to 4 cm. The master and slave are both STM32 MCUs. If this is a risk, is it worth bringing both to an interface board and have a driver in-between? If so can I use something like SN74AVC4T774? Please note the logic level on both PCBs are 3V3. So no level translation required.
Thanks
Regards
Billy
