SPARKY-2B: A Basic version of Sparky-2 CDI Ignition Kit

Sparky-2B is basically the same as the Sparky-2 ignition except it doesn't come with the components for input noise filtering or the temperature compensation, saving you some money. Other than these differences it is the same kit minus the extra parts. It also uses the same HV board as Sparky-2.

Sparky-2B has as many parts as possible as through hole (PTH) so that the user can solder up their board. There are some parts that are SMD (surface mounted devices) but, these will be soldered onto the board so you don't have to worry about them. The kit will contain all the parts needed to complete the boards. As for pricing, that has not been set yet.

The main features of Sparky-2:

Batteries you can use:

Use a 500maH or greater capacity battery, the circuit will draw a max of 1500ma if you let it but, a current of 500ma or less is normal. I use a regulator so you can use 6 - 18 volt NiCad, NiMH, Lithium Ion / Poly / LiFe but, you should use a volt monitor so you don't wreck the batteries. A battery voltage as close to 6.0 volts is best to reduce heating of the regulator but, with higher voltage & maH you can fly longer (hours) before recharging. The regulator is a surface mount device and is a LDO (Low Drop Out) linear regulator that cuts out at 5.3 volts. Recommended battery volt range is 6.0 to 13.5 volts.
