While I take great pride in my work, I am no professional but just a good willing amateur. Therefor I have to warn you that if you decide to use the info on this blog or order some of my "product's", I cannot be held responsible for any kind of damage, burning down your cab/house/city or following addiction to pinball games in any way.

In other words: use is at your own risk !

Arduino driver board

I have designed a PCB to use with the Arduino board so that you can drive more powerfull toys with the Arduino board.

Each PCB has 12 inputs and 12 high power outputs that can be used separate from each other. You can feed the PCB with 12 and 5 volts and via a jumper decide for every single output if you like to use 5 or 12 volt DC. The maximum output per port is user defined by changing the diode. The default is max 16 amp with the MBR 1645 or you can downscale it with a other diode if you like. If you change the 560 Ohm resistor to 1K2 you can also use the PCB for 24 volts.

Beware: It is not recomended to switch this high amps for a long time with the PCB

The driver board will only switch on positive voltage, not negative like the LEDwiz. If you like you can invert the signal with an optocoupler (1N35 or so) and still use it with LEDwiz. If there would be enough demand I could also design an PCB for that.

If you like you can order the PCB from me. I also give the option to order the parts needed and final option is that i solder the board for you. Offcource this takes some time !
Important remark is that I do not do this to make money but just as a service to the community. But you also might understand that I don't want to lose money on it (ordering parts and let them collect dust) nor want to spend my valuable time for totaly free.
Having said that please understand that I do not offer next day delivery as I have to probably order the parts also and in some cases a new batch of pcb's. Contact me first on what the current status is of supply's.
