power extender

[Darth Vapour]

Hi, sorry if this has been covered but i couldnt find it. Can you use the power extender plus a resistor with the econo hasbro board instead of a transistor and buckpuck?

[Silver Serpent]

Yes. The power extender will do the job of the transistor. Resistor or buckpuck can be used with either configuration. The PEX costs more than a PNP transistor, which is why it's not normally used with a budget setup.

Transistor and resistor is the least expensive way to do it.

Thanks, i wasn't sure if you could go resistor with transistor, thought you needed puck which is more expensive. If running a ledengin can you get away without resistor running the 1.5A from the pex directly?

No, the PEX doesn't regulate current. You'll need a resistor with it.

Thanks. So what are the benefits of the pex?
