3. Insert all the resistors as shown in Figure 8. Use an ohm meter or refer to the color banding to
determine the values of the resistors. The orientation of the resistor is not important.
4. Insert the Rectifiers. Orientation of the rectifier is important. It will short the circuit if put in the
wrong way. The lead that comes out of the side of the rectifier with a line on it should go in the
square pad hole.
5. Insert the capacitor as shown in Figure 8. Orientation is not important.
6. Insert the 8 pin IC socket. The orientation is important. The notch should be towards the
bottom of the board so pin one is in the square hole. Refer to figure 8.
7. Install the Screw Terminals (if provided) as shown in Figure 8.
8. Insert the Relays as shown in Figure 8.
9. Insert the high current driver IC. The orientation is important. The chip will be shorted and will
not work if put in wrong. Pin one goes in the square pad hole such that the notch on the chip
is closest to the label on the board. Refer to Figure 8.
10. Insert the 8 pin preprogrammed. The orientation is important. The notch should be lined up
with the notch on the previously installed IC socket. There is a dot on the IC, its pin one.
11. Attach the RC signal, ground and 5V to the board. You can power this board from the RC
receiver if desired, although a regulated 5V source is best. If the RC receiver is being power
from a non regulated source, such as a battery pack care must be taken. Most NiCad or NiMH
will only output 4.8V, which will work fine. If using 4 alkaline batteries, your voltage will likely
be above 5V, and the board will not work. This can be solved by using the supplied resistors.
The resistor should be put between the supply voltage line (the red/orange line) and the 5V
terminal input on the board. The list below shows the acceptable voltage ranges with and
without resistors.
• 3.2V to 5.1 V, no resistor
• 4.5 to 4.9V, 47 ohm resistor
• 5.9 to 6.7V, 100 ohm resistor
12. When the board is 1st powered the yellow LED will blink for about a second. If a RC signal is
not present the yellow light will blink fast. If the RC signal is in neutral position the yellow light
will be solid. When the RC signal is ~1/3 up or down, the either the SPDT relay will turn on
(turning the load on), the opposite direction will result in both relays pulling in (reversing the
load and turning it on)
13. The LED should light and the Relays will pull in as stated above. The SPDT relay (Input 2)
pulls in the power, the DPDT relay (Input 1) reverses the load. Pulling in only the DPDT relay
will have no effect. The limits must be made up to complete the circuit. Start by jumpering the
limit S1 to S1 and S2 to S2, then as the load is driving remove the jumpers to determine which
