The side connection pads on the Progrock2 board may require some precise soldering skills. An alternate way to connect to the board is to use a "Edge" connector. The board requires a 12 pin connector which should have a pitch of 2.54 mm or .1 inch. The Edge connector facilitates easy connections and also allows you to remove the Prog board from your current project and reuse it on another project. A larger/longer Edge connector such as a 36 pin can also be trimmed down. Observe caution when inserting the board make sure that the Positive supply voltage goes to the correct pin.
