Very simple question I hope, but my searches have failed. What's the best way to access unused GPIO/data pins on a Mega while a (NON SPI) tft shield is in place.
For example if I want to access SDA,SCL and the other unused tx/rx pins .... I am not keen on soldering on to the mega if I can avoid it.
Can I add more pins to the shield that then plug into unused pins and then solder to the shield.
This must be a common problem e,g adding clock, temp or wifi modules to a TFT set up
