20160819_142809Solder Side
20160819_142842Start by inserting the 8 pin IC holder, ensure that the cut out at one end matched the cut out on the board silk screen. Carefully solder the pins on the solder side of the board, being careful not to bridge the pins with solder.
20160819_144235 Select the three resistors 100K(brown black yellow),330R(brown black brown) and 100R (brown black brown)
20160819_143844Insert the resistors into the three resistor places shown and solder.
20160819_144330Insert the diode into its place on the board. Ensure the end of the diode with the white line matches the identification on the board
20160819_144620Insert the 4 capacitors in the position shown
20160819_144526Insert the regulator, Ensure that the D shape of the regulator, matches the D around the silk screen. If you are running on batteries you may want to leave out the regulator look at the use guide for more details
20160819_144854Insert the LED match the Flat of the LED with the Flat on the circuit board. and solder in place
20160819_145234Insert the two push buttons and solder in.
20160819_150402Insert the transistor in to the holes shown
20160819_150430Ensure that the tab is the same way around as shown on the PCB
20160819_151214Insert the capacitor checke that the -ve leg designated by the —– on the side of the can
20160819_151131Matches the -ve on the capacitor ident on the PCB

20160819_151220Add the two pin headers into the solenoid button and power connectors. Leave the header out of the 5-6V position unless you are using the alternative supply arrangement detailed in the use guide

Your board is done, enjoy…
