Universal Proto-board PCB 6cm x 8cm - 2mm pitch
Here's a handy 6cm x 8cm Proto-board PCB that is meant for use with 2mm pitch parts - like maybe an XBee. Both sides have a green silkscreen with some row/column markings. Note that these don't have any traces between the PCB holes; you would normally bend over a thru-hole lead to create connections. They're also good for just plain mechanical work because they are made of strong FR4.
Contains 33 X lines by 26 Y lines totaling 858 holes. There are also four mounting holes so you can attach the PCB to your project box.
Please note: this proto-board is designed with 2mm pitch not the standard 2.54mm / 0.1" pitch you may be used to!
