    Someone from the different forum communities suggested me to use the solid state relay(SSR) instead.

    Compared to the mechanical relay,  the SSR requires only small amount of current(A) to activate so it will cause much less stress on MFC-03.

    I will test out the SSR once I get all the circuit parts I need and let you know if I succeed.

    You don't have an extra channel on your radio I take it. Pico switch works great for this, if you have radio space. Your on the right track. I wish I could help more, but nothing, I know of is made for this. Maybe an audrino would work, but I don't know much about them.

    Your help was more than appreciated and I thank you again.

    Might find something here...

    I am afraid that I still don't have enough knowledge on MFC-03 LED port to pick the suitable switch unless the product specification state that the product is specifically designed for MFC-03 LED port.

    But thank you for your kindly suggested link page.

    I thought about this and remembered I saw something that might work? It is called a "MFC Expander Board". I would put Tamiya in front of that for web search. I have not tried this, I don't see it working with what I know about the MFC. May be it has some circuitry in it to makes it work? It is supposed to plug in to MFC and give you 10 extra plugs to plug in. Not much info on it , does it work?? Note  it is not made by Tamiya as far as I know. This may work for you? About $23, I've seen it on Ebay and a hobby store. 

    Let me know if you need help finding it? If it works let us know. Remember MFC's are expensive. Just trying to help.

     

     

     

    First of all I thank you so much for your long and kindly detailed explanation.

    I already looked into "MFC Expander Board" and although I couldn't understand how it works it's main purpose of the usage seems to expand the number of the LEDs connected to the one MFC port. As you already understand I simply need the solution to "How to connect one 6V~7.4V LED to currently empty MFC J20 port" and this board doesn't seem to fit my needs.

    I saw some relay module that operates on very low voltage (below V5 maybe?) but I couldn't even figure out the MIN. and MAX. voltage that can be drawn from MFC J20 port safely.

    Hello,

    I am fairly new to the electronics and I need help on connecting a light bar to Tamiya MFC-03.

    I wish to power up the light bar using a main battery (7.2V, parallel split wiring) as a power source and MFC-03 (J9, J16, J20, J27 LED ports are available and planning to use J20 port) as a trigger.

    During my brief research in this forum I found something called "Pico Switch" from Dimensions Engineering. But if I understood it correctly it uses servo port PWM instead of regular LED port (such as J20 port) voltage as a trigger and this was not what I was looking for.

    As far as my knowledge goes my only option is to use a relay switch but I don't know which relay is safe to use directly on MFC-03 LED ports.

    If possible could someone please pinpoint the suitable relay switch I can safely use  on Ebay or someplace simular? (a seller who ships internationally)

     

    Thank you.
