@Bret.Tallent I would not consider modifying the board. If you make a mistake, it's ruined. That'd be a pricey mistake

The additional power module should be available in a week

cool! Can't wait! Thank You

why not run power for your fan direct from battery. you can use a switch to trigger one relay to turn on ez b and another relay to turn on any other powered components, that way power is not coming from ez b and you will have a easy on off switch for your bot. i can give you directions and schematic for wiring. it may sound complicated but this is how we power pretty much anything in automotive customization.

@jstarne1 The relay will draw more current than the fan. The problem is he was running all of those peripherals off the 5 cell standard battery pack. That's only 1 amp, at max. I doubt it's even 1 amp with AA's. He'll be fine with a more powerful battery pack. I think the dudes that use lipo's know where it's at. They get 3-4 amps out of those things, and they're tiny and light.

We should start carrying more powerful battery solutions.

I got a Thunder Power RC LiPo from local RC shop 910mAh works great, size of two AAAs.

Using a transitor to turn stuff on and off is really easy.

1. Get a TIP120 Darlington Transistor.
2. Connect power to whatever you want to turn on and interrupt the ground with the "emitter" and "collector" from the transistor.
3. Connect a wire from the PWM of one of the Digital ports to the "base" of the transistor.
4. The circuit will be open (off) until you switch the digital port to HI which closes the circuit and turns your device on.

A TIP120 transistor from Radio Shack is less than $2.

Maybe i should turn one of those into an ez-bit.. give it 4 or 5 channels. put a filter on it too.

@DJ -- I thought we had a deal! I'd answer the easy questions and you'd get more product and features out the door!
