Access GPIO's directly from expansion port

Access GPIO's directly from expansion port

Hi,

I'm working on a project involving the TinyScreen+ and the EEPROM board.
I plan to remove the bottom expansion port of the EEPROM board to save some millimeters in space. and this way can access the pins easier, which brings me to my question:

Is it possible to hook something up to the IO8 pin (25 on the connector) directly?
I plan to attach a piezzo buzzer for 8 bit audio and want to save as much space as possible.

Ok found my own answer:
Yes.

The pins available on the proto boards are directly accessible on the expansion port.
It is very tricky and difficult to solder to, but possible.

My approach:
I've used the plug of another board, removed all pins but the one GPIO I wanted to use and the two GND pins, then soldered the buzzer to the pins and plugged it in. Works flawlessly :)
