Applications

High power smoke unit  is getting more and more popular in RC tank to generate more smoke, because the current could exceed the specification of smoke unit port on tank controller, a switch module can be introduced drive high power smoke module  thought CN10 and CN11 port, the following is the equivalent circuit of CN10 and CN11 port, when engine sound is turned, software controlled switch is closed to battery+, so the CN10.1 pin can be the control signal of switch module, connection table below shows the detailed connection. CN11 must be closed by jumper.
