Ground pads, seven (yellow) pads
+9V supply, two (magenta) pads
Wiring to the Circuit Board Input
Wiring from the Input Jack
Wiring to the Output Jack
Wiring from the Circuit Board Output
Use either Common Anode or Standard LED.
LED Options! - Use a Standard LED or use a BiColor.
(7) Grounds conveniently located - instead of (5). Great for Multi-Pedals.
Great for Combo-Pedals.
(2) - 9v Power Pads for more options and convenient wiring of LED.
LED is now completely mountable on the board providing a firm connection and less wiring. Check Layout!
Convenient Corner Cuts allow for use in small builds or carefully fit (2) side by side,while still maintaining alignment.
Plastic Bezels are recommended for Common Anode LEDs. Bezels and LEDS are in the PCB Shop!
The value of the CLR (Current Limiting Resistor) is not critical. A value of 3k3 is suggested as this
offers a good trade-off between LED brightness and current drawn. Choose values between 2k
(brighter, more current) and 4k7 (dimmer, less current) according to taste.
The 3PDT CC Wiring Board uses a common cathode bi-colour LED
The pin-out for the bi-colour LED is as follows:
90 degree bend in the lead
1st Colour Anode
Common Cathode Middle lead
2nd Colour Anode 45 degree bend in the lead
Using a Red / Green LED and wired as per the wiring diagram, the LED will light red showing that
power is applied to the circuit board and the switch is in bypass mode, it will light green when the
switch is in effects mode.
GuitarPCB supplies a common cathode bi-colour Red / Green LED with every 3PDT CC Wiring
Board sold. Should you wish to use a standard LED instead, the anode is soldered to the left hand
pad and the cathode to the middle pad.
All the other Unique advantages of the Original such as:
Audio wires kept separate for less noise & cross-talk
Small footprint with space saving corner cuts.
On-Board Current Limiting Resistor for LED.
Symmetrical design that matches your internal pedal layout
Eliminates the need for tricky star grounding.
Handy on-board symbols and more....
Note: If using a Standard LED place the Anode Leg in the center hole of D1
then place the Cathode Leg in the hole to the left of it. (Not the White one)
Wiring
So long as the 3PDT Wiring board is grounded at some point, any of the ground pads may be used.
One of the 9V pads is connected to the +ve power supply while the other pad can be used to run
power to the circuit board (or connect the circuit board +9V pad directly to the power supply).
Probably the easiest method is shown in the following diagram using the AEON DRIVE v2 circuit
board as an example:
The ground wire between the 3PDT Switch Board and the Aeon Drive v2 can be run between any of
the free ground pads, the input jack ground pad on the Aeon Drive v2 is the closest.
The +9V power supply pad on the Aeon Drive v2 is taken from the second 9V pad on the 3PDT
Wiring Board.
When using the 3PDT Switch Board with the Aeon Drive v2, the pads S4, S5, S6 and D5 are not
used and R10 is not installed.
Unused pads and components will be detailed for each circuit board project in their respective build
documents.
