Transistor board was designed as a doughterboard to Lan Controller board and fit toghether in housing.
It contains 4 high power MOSFET transistors, which can supply load up to 3A. We can manage outputs OUT1-4 from Lan controller website: switch on/off powered from this board supply input. After switching on we can controll PWM duty cycle and this method change output power of load, for example brightness of LED strip connected to transistor output. Controlling PWM for OUT1 is possible directly from Controller website, other outputs can be changed only by http requests from web browser or smarthone app.
Maximal load is 3A if use only one output or 1A if use all ot them.
Doughterboard has 0.1ohm resistor for current measurement (connected to INP4) and resistro divider for voltage measurement on INP5.
Supply connected to this transistor board can supply Lan Controller but not in inverse way.
