Template:FAQ/Questions/pin to pin spacing

What about pin to pin spacing and pins on the expansion boards?
e.g. Is the hirose adapter a very small adapter (pin to pin distance ?) or is there something to adapt it to a 2,54 mm pcb ? Does one of the expansion boards offer a full, or at least partial, access to pins of the hirose ?

The hirose connector is a very high density connector (0.5 mm pitch).

The waysmall board has access to 20 GPIO pins (you can see the pads in some of the pictures on my web site). These pads are spaced at 0.1&quot; spacing (2.54mm) ina double row. You should be able to solder on a surface mount header.

The ThumStix? has a single row of 8 pads.

The SMT breakout board has a series of connectors to get at most of the signals. There is also an unpopulated spot at the end of the board for a high denstiy connector (0.5mm pitch).
