Original thread got lost in the forumcrash.
I have made a sensorboard that is under testing.
spec:
socket for arduino pro mini 5v/3,3V
socket for radio
3,3v regulator
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?
I am also interested to participate if the meeting is is someday between 2-11 july as I am visiting skåne then.
@Vodden how large is your enclosure?
I am working on a daughterboard for my mys1.1 with 4 channels of pwm and current measuring on each channel.
each board is 50x50 mm stacked on top of each other.
I now have 300 boards on my desk and have set up an online ordering system on my page http://www.sa2avr.se/mys-1-1/
After a discussion with @hek have I also released the board files for mys 1.1 on my page.
@ludoarchi Please try again.
I had edited the page to much last night.
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.
