Switch module
Overview
-
Switch module
can be used to drive high power devices, such as motor, low resistance smoke
unit heater, high brightness LEDs, from low power singles on RC tank
controller,
-
Battery voltage from 2S to 3S,
-
LED indicates the state of switch.

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

Automatic cannon light and
smoke
The diagram below shows how to
drive automatic cannon light and air pump by a switch module by CH4 port on AATK50. R1
is used for current limitation. about 200 Ohm for White light LED, D1 is 1N4001
or equivalent.
