Hi there i am working on a 6WD UGV using arduino unos and xbee 900mhz for communication.
However i have a problem. The Xbee 900mhz requires 3.3v @210mA but the arduino can only supply a max of 50mA. And so my xbee range is extremely reduced to the point it is unusble.
So if anyone has any idea on how i should power it i would be very grateful!
And once i bypass this problem i would upload my full project!
I'd get a 3.3V voltage regulator and a couple of caps, and tap the same power supply that is powering the Arduino, and create a 3.3V regulated power supply. YMMV.
