Power Netduino (Linksys WRT-54Gl)
Posted 15 June 2011 - 05:36 PM
Is it possible to power the Netduino by a Linksys WRT-54GL router? Both devices use 12 volts, but is it enough if they have to share? I'm gona put the Netduino inside the router and hope that there's no need for two cables:)
The Netduino also has to power four fans, a lcd display and a couple of servo's.
What is the proper way to connect the router and Netduino? I saw on internet a way to power the Netduino through the Vin port...
Thanks in advance

Try it and see. A long a you get the polarity right the worst that will happen is that one or both devices will reboot.
I recently tried to power a router and a BAD from the same power supply and got occasional resets sure to lack of power.
Not really, if the voltage is too high you risk toasting both devices. A reset from power would not indicate a lack of power, it would indicate something is wrong with the supply or something is doing something bad to the supply, such as shorting it or introducing noise on it.
Power supplies do not have hard limits of how much current they can source. There is no firm line that you go over to cause things to fail. What will happen, is that the more power over the limit of what the supply can source you go, the hotter or more unstable the supply will get until it either burns out or does something else bad.
Hooking something so trivial up as an Netduino up will not cause anything like that adapter to overheat.
