Explain the role of each card

I will try to explain what is the purpose of each card I sell on this site.



You know the  KL25Z , this card that is the heart of your Pincab? 
The  KL SHIELD  will facilitate you and secure wiring your  KL25Z  by being inserted in the Pins of the KL25Z, and thus provide small terminals on each input and output of it. 
No more Dupont solo cables that do not hold in place and disconnect when you repair your pincab.

In addition, this card is equipped with a capacitor and a resistance that will allow you to avoid the shaking of your Plunger, which you will have connected to its dedicated output.

You have at your disposal a configuration file that allows you to wire 21 input buttons (more than enough!) On the terminals that are marked on the  KL SHIELD . Pretty practical!

And if you decide to use one of my extensions, I planned a dedicated plug for even more make your task easier ...

This card does not replace a KL25Z, it comes to put on it!



In a Pincab, there is electricity circulating. 

Who says electricity says protection, for that we put fuses on each toy, to protect the toy, to protect the feeding, to protect the pincab, and to protect itself.

In order to simplify all this, and save space, I make FUSEBOX , cards with 16 fuse holders in 5x20 format and small screw terminals in and out to facilitate and secure the wiring.

I also sell the  fuses that are lodged in it.

WARNING, we do not put any fuse values, it must be calculated, and all that depends on the toy you will connect it.

The value of a fuse is calculated in Amperes. it must always be a little higher than the maximum consumption of the toy that will be connected to it. 
The role of the fuse is to melt if the toy consumes too much current, and thus cut off power to the latter.

Take the example of a toy that consumes up to 4 amps of its use. We will protect it with a fuse of 5 amps, like that hopefully, the toy will consume its 4 amperes, which will cross the fuse without any worries, but if unfortunately a short circuit occurs at the toy, or there is defaults and begins to smoke, its consumption will drastically increase, at this time, the fuse is crossed by a current greater than what is supposed to pass, and at 5 amps it will melt, cutting the power of the defective toy, protecting the power supply and preventing the toy from taking fire, for example. 

To calculate the consumption of a toy, it is necessary either to look at the documentation of the latter and to find the values, or to measure it by means of a multimeter in series in position Amp-meter, or by means of a current clamp. You can also ask on Facebook or forum groups if someone with the same toy knows his consumption.

If on the toy we only find the power in Watts, just use the formula you must know by heart: 

P = U * I

P is the Power in Watts, U is the Voltage in Volts, and I is the Intensity in Amps.

if we have a 10 Watts toys that works in 12 volts, so we make 10 W / 12 V = 0.83 A, we will use a 1 ampere fuse to protect it.



To control your toys, you have to go through Mosfet Transistors because the KL25Z can not control toys that consume too much current. This is the KL25Z who pilot this Mosfet and told him to turn on, extinguish, or graduate the toy.

This card has 8 Mosfet transistors, so you can control 8 toys connected to 8 outputs of the KL25Z .

Each mosfet line includes:

  • a resistance to not draw too much current on the KL25Z (This resistance is not on Chinese mosfets cards, which suddenly heat your KL25Z, thus reducing its life)
  • An optocoupler to completely separate the voltages side KL25Z and those side toy
  • A mosfet that can handle voltages up to 50 volts
  • One 5 * 20 fuse holder

Each track can support a maximum current of 8 amps, and the board can support a total current of 20 amperes simultaneously.

We can drive toys of different voltages with the same card because the control is done on the negative terminal of the toy.

The wiring is facilitated by the terminal blocks which are all marked.

This card uses Digital and PWM outputs available on your KL25Z


Extension Extension

This card is actually a kit consisting of 2 cards, the one below which is the extension, and the one above that is the card fuse holder in the format optimized for the extension.

It allows to simply add 16 PWM (modular) outputs to a KL25Z , all on Mosfet and fuse holder, thus increasing the possibilities of the KL25Z in toy management.

It uses 5 outputs of the KL25Z (including one PWM).

We can connect the extensions one after the other, and thus add even more PWM outputs to drive more and more toys.

The same card can drive toys of different voltages because the control is done on the negative mass of the toy.

Each of the 16 mosfet lines includes:

  • An optocoupler to completely separate the voltages side KL25Z and those side toy
  • A mosfet that can handle voltages up to 50 volts
  • one  5 * 20 fuse holder

Each track can support a maximum current of 8 amps, and the board can support a total current of 40 amperes.

The fuse card has connectors for easy installation and maintenance of the kit

You find your outputs numbered on the card fuse holder



PinMos is a shield (card support) that allows to cleanly and safely wire a Wemos card to control addressable LED ribbons (to make a backboard, sideboards or other nice things ...)

 Wemos card comes on the PinMos card.

You have 6 signal outputs to control 6 different LEDstrips.

Each signal output is equipped with a 220 Ohm resistor, which can be activated using a micro switch. (Resistance is essential in some configurations).

You also have two screw terminals to connect card's ground.



VoltBoard is a card for managing the 5  Volts power supply of addressable LED strips for backboards, sideboards and other small flashing things ....

Each length of 1 m of addressable LED 144 consumes 8 amperes. 
It requires a power supply line per section of 8 Amps because LED ribbons can not collect more current

We plug our 32-amp power supply into this card, and we have 4 8-amp outputs available, each protected by their fuse (supplied) in its fuse holder.

Each board has a capacitor to smooth the voltage, and 2 terminal blocks to connect ground to the control board ( PinMos )

Your installation is thus clean and secure.



It allows you to connect your STM32F407 board to your 2 DMD panelsto build your ow PIN2DMD

2 buttons to navigate trough configuration menu of your DMD and thus make your various settings (type of panels, DMD brightness ...)

With this shield, No mode DUPONT cables, secure and fast !



USB KILLA allows you to turn off the power of your USB devices when your PC is turned off.

Connect the card between your USB devices (or your USB HUB) and your PC, so when your PC will turn on it will feed your cards (KL25Z, Wemos, ....), and at the end it will cut them, in order to protect them.
