Quad-PIC and Accessories
Quad-Pic Servo DCC Accesory Decoder
Use to control four turnouts using model R/C style servos. Servos are easily mounted under the turnout and provide a reliable and inexpensive method to switch points. the Quad is very versatile, you can move the points by DCC commands from your throttle, use buttons on the fascia, control from a signal system or any combination of the 4. LEDs can be hooked up to indicate the direction of throw.
DCC - The unit can be completely programmed from the buttons and LED indicators on the board or you can use programming on the main to set the CVs. The DCC address is easily programmed by setting a jumper and then issuing the desired accessory address from your throttle. This avoids the confusion of how DCC Accessory addresses are stored in the CVs.
Power - The board has a beefed-up and separate regulator circuit for the servos to eliminate power loss to the microprocessor. The best way to power the board for DCC is to use the specially designed DCC Accessory booster which can power up to 6 Quad-Pics. For DC use any power supply from 7.5-18V AC or DC can be used. It is also possible to supply 5V power directly to the servos. The servos are completely opto-isolated to prevent ground loops.
Expansion - The new design has provisions for adding daughter boards to expand the capabilities. One daughter card has relays for switching the frog power or controlling some other accessory. Another daughter board lets you add on stall-machines (such as the Tortoise™) - you can still use the servos at the same time.
Signals - Inputs for signal systems have been added. An expansion board that provides full opto-isolation of the signals is available soon. Download the Quad Servo Driver Manual

LEDecoder - 3 Output Lighting Decoder
This handy little DCC decoder can be used to drive LEDs in a variety of lighting applications. It can be used to drive 3-LED signal heads or individual LEDs. No external resistors are needed as they are on the board. You can control the relative brightness of the LEDs with CVs as well the turn on and off rates. it is set up for JMRI - type Double Output. Can also be used to light a building or a passenger car. With the flicker function it can imitate a flickering light bulb, a welding arc or a campfire. Although the outputs are marked R Y G for ease of wiring to a signal head, any color LED can be used. In addition there is a mode for driving a 2-lead bi-color LED.
The decoder uses 2 consecutive DCC addresses - one controls the R output and the other controls the G output. If both are on then the Y output is lit.
This handy little lighting decoder has numerous uses. It uses 2 DCC addresses and has built-in resistors. Can be used with JMRI for signaling. Can also be used for DCC controlled lighting of buildings and passenger cars. The flicker function imitates arc welding, flickering lights and fires. Size: 1.5" x 1.0".
Singlet II Servo DCC Accessory Decoder
The simplest and quickest way to get servos up and running on your layout. Features an integrated controller/programmer/DCC decoder/power supply and servo driver in a tiny 1.25" x 1.25" board. Comes with a servo and a servo extension cord - simply plug in the servo and connect the unit to your DCC power bus and the wiring is finished. The board mounts behind your fascia through holes drilled using the drilling template. The servo endpoints are set using a unique automatic endpoint adjustment. You can also use the buttons to set or fine-tune the endpoints as well as setting the LED colors. The DCC address is easily set by holding both buttons and then sending an accessory command. The unit memorizes the address. The unit can be used without the DCC on DC layouts by using an AC or DC power supply.
Besides turnouts, the singlet can be used with servos to animate semaphores, crossing gates and other items on your layout.
Singlet shown with optional SG90 Servo (right) and Remote Relay (left)
Bi-Color LEDs - Gives you full control of the indication color for each track. Each LED can be set to one of 4 colors - red, green, yellow (red and green on simultaneously) and dark(off) for each position. For example you can indicate the open track with green and the closed track with red, or you could use green/yellow, or you can have the open track be green and the closed track be dark. Any combination is possible - it is up to you!
AutoAlign Feature - The new singlet can find the servo endpoints on its own, they no longer have to be programmed with the buttons. By setting the Align jumper, the singlet will start at the center position and slowly seek to both ends until it finds resistance from the stock rails. At this point it backs off slightly and remembers the position. The algorithm has been carefully tuned to work with both standard and SG90 servos and with hinged point and solid point turnouts. Works great with the mounting kit. It will also work with other devices as long as there is a hard stop at both positions.
The singlet can still be programmed with the buttons if for some reason the AutoAlign does not find the desired positions.
Remote Relay - Add the remote relay to use for routing frog power, for adding feedback to signaling systems, or for trackside indicator lights. Choose either SPDT or DPDT. The relays use the same extension cords as the servos for simple wiring.
New in v2 (July 2011 and later) -Programming buttons can be locked out with a jumper to prevent accidental programming be leaning on the buttons. Auto-align current setpoint can be changed with a CV (CV50).
SInglet flip side showing how servo plugs in to board.
LEDs are bicolors even though they appear yellow in this picture. No servo included.
Singlet II+ Servo Decoder Does not include servo. Includes PC board with control.programming buttons, mounting screw and instructions. To control a turnout we reccomend you also get an SG90 (SRV002 on Servo and Accessories page) or similar type servo. Another servo that works well is the Hitc HS-311, which is a standard size servo, good for animation projects and large scale applications. For controlling a frog or other accessory with a relay use the RDR001 (above).
SSD002 $24.00 USD
Video of Singlet Decoder including programming the endpoints and the DCC address as well as how to prepare the servo.
Note: since this video was made I have added the ability to change the speed of the servo and set the LED colors. After programming the endpoints the colors of the LEDs can then be set and after that the LEDs will flash alternately and in this mode you can change the speed of the servo from a dead crawl to very fast.
Turtle - Accessory Decoder for Stallmotor Switch Machines (Tortoise, MP1, SwitchMaster, etc) with Speed Control and Local Lockout
This item includes board and mounting kit. For local control you will also need a Fascia Controller (this page). For connecting to a motor the options are to use the jumper wires below, your own wires soldered to the output pins, or a servo extension cable. The MP1 motor requires a 3-wire connection so the servo cable is a good option. The jumper wires connect directly to the the M1 and M2 output pins on the board. The wires can be plugged in to each other to extend the distance beyond 12". The Turtle w/ Fascia Controller and a Tortoise draws about 10 mA (0.01 A) of power.
Size - 1.15" x 1.25" (29mm x 32mm)
Max Power Supply Voltage - 20V
Max Motor Drive Current - 1A
Max LED Drive Current - 20mA
Max Load Controller Port 5V pin - 100 mA
Change in lockout address - as of Aug 2017 the lockout address is the base address + 1000. Previously it was +1. The change has been made to allow easier integation with existing DCC address spaces. Consult your documentation to see which version you have.
