Title: Sparky 2 and Retract Gear
Post by: Marduk2004 on July 22, 2016, 04:49:20 pm

Does anybody know, how to Connect a Retract PWM Signal to the Sparky 2, for switch with AUX1 or 2?

For Sparky2 or any board you can affect a switch to one output, like for a buzzer:

You may take a look at the last column "Response Time" for the Accessory mapped with your switch, can be useful for gear.

The Problem is, i used all 6 Output's for a Hexa. Is there any Option to use the LED Out's?

7 to 10 are on Led connector

Because buffered you cannot use directly the output signal for servo.
Adding a pullup resistor give a PWM signal but inverted.

Solution can be add a small wire connected before the N-Fet, connected to a servo connector attached to board with hot glue or similar.

Is Channel 7 to 10 supported in the RC1? I try to use the PWM Signal before the N-Fet, but it doesen't work. I set the right RC Input to the right Channel in Output...

The LED output port works, you should pick the signal just before the mosfets for normal PWM output use.

Ok Thank you, it work's yet. There was a problem with the Neutral in the Output Tab

Just a quick comment about the NFETS on an HK Sparky 2.

I have 3 originals but cant seem to get them any more so i went down the HK road and have found that the 2 nfets are only connected on 9 & 7 on the above diagram with the board that i bought from HK.

I was testing an inverter board that i made, works fine with the original but not with HK thats when i started to do a little digging.

So looks like i'll be making my own sparky 2's from now on. If any one is interested in using 7-10 ch on sparky 2 let me know.
