RE: irlz44n not fully open using 3.3V Arduino
Many mosfet does not open fully on 3,3V. You have to check graph in datasheet when choosing mosfet.
You can pull gate high with a resistor to 12v and use a npn transistor to pull it low.
But that makes it default on. If sensor node fails all leds will be at 100%.
My ledmodule uses IRLR2905 and is powered by a 5v promini.
My sensorboard MYS 1.0beta
Original thread got lost in the forumcrash.
I have made a sensorboard that is under testing.
socket for arduino pro mini 5v/3,3V
socket for radio
4 AD input with voltage dividers
7 gpio availble with pullups on all pins
I have som small mods left to do in the voltage dividers.
Is there any interest in boards or kits (board + components) for just a few dollars?
