Topic: Connecting Pins in Arduino Mini Pro Header (Read 791 times) previous topic - next topic



I am creating a PCB that will connect to a Arduino Mini pro. Do I need to connect the header pins to the equivalent pins on the sides? For example, should the ground pins of the header be connected to "GND" like the pins on the sides that I use as ground in my circuit?

I know that the header is only used for uploading code to the Arduino, which is why I didn't think the header pins needed to be connected to anything in the schematic. I've attached my schematic, could someone confirm if its correct?

Thank you!


Yes, you can leave those isolated and just put on pins for an FTDI Basic to plug onto.

5 of 6 are directly connected internally already - Gnd, Gnd, 5V, Rx, Tx - only DTR is not, it goes thru a 0.1uC to the Reset pin.
