9V Powered Netduino


Best Answer Chris Walker, 31 January 2014 - 11:06 PM

Hi Darduino, As renatoa mentioned, Netduinos have power supply auto-switching. So when you plug in power via the power barrel (or VIN pin), Netduino will automatically switch from USB power to the your dedicated power supply. Chris Go to the full post

Hi everybody,

 

Is it ok to power a Netduino 1, with a 9v battery via the power jack while connected to your laptop through the USB. How will it handle the two power source?

The U1 comparator sense the power jack presence and make the switch between USB and jack power using the Q4 FET switch.

Thanks all,

 

Netduino is not giving enough power to my Wifi and GPS module, was going to power through power barrel but was not sure of the effect since I don't have the schematic

 

guess I'll pump up the power!!

Hi Chris,

 

Why are there no links on the site to materials on Netduino-1  and Netduino Mini :( . for some of us that are still in love with N1, it will be nice if we can still get some reference material from the site.

 

and I really think the mini should get some upgrade, it would've been the perfect foot print for my current project

Hi Duardino, Wi-Fi and GPS may take quite a bit of power, combined together. Do you have a dedicated power option for one or both of them? Netduino can deliver up to 800mA of power if you provide power via the power barrel--which is quite a bit, but not an infinite amount of power. Links for Netduino 1 and Netduino Mini: http://www.netduino.com/netduino/ http://www.netduino.com/netduinomini/ We're evaluating a 4.3 upgrade for Netduino Mini. It's a pretty awesome little chip-board. Chris

Thanks Chris for the link.

 

Yeah just realized that even if I power via the barrel I will be limited to what Netduino can handle (800mA) now I don't know if that will be enough for the Wi-Fi / GPS Combination

 

Since I have some 7805 voltage regulators  around, I'll just build my self one and power the Wi-Fi / GPS with it.

 

A 4.3 Netduino will sure be great!! more so if we also get a mini-2 that will come with One GoBus Socket that will support a Shield base and GoBus Hub ;)
