Q. can i control more than 1 servo with this unit
A. Hi Bill, thanks for your question. In theory it may be possible to control more than 1 servo if they are connected in parallel and are similar units – but they will but work at the same rate and share the current between them so its effectiveness is divided by the number of servos attached – it would also be easy to overload the circuit. We hope this helps.
Q. When I used this to power a HV Spark Coil from RMCybernetics, the power was so low, it only just drove the coil. Is there any chance I can configure this pulse width modulator so I can make the sparks a lot bigger? I have to scrape it along the wire at the moment in order to get a small spark. I can't afford to buy another board.
A. Hi Owen Thanks for your question. The unit will only vary the pulse rate of the input voltage, ie change the time between On and OFF – it will not amplify it. If you need any further help please feel free to contact our technical department tech@rapidelec.co.uk
