For those in the US: Fry's has 5V 1A USB chargers from Belkin on sale for 30 cents a piece! Perfect for powering the odd electronics project. http://www.frys.com/product/6517763 According to this test and teardown, it seems to be living up to its spec: http://www.eevblog.com/forum/reviews/teardown-$0-30-usb-power-supply-at-fry%27s/msg671559/ The catch? The connector on the USB cable is for obsolete iProducts. So you even get a solid USB cable that can be cut up without regrets. My local Fry's in Renton, WA still had a few hundred on stock at 3pm today. I don't think they will last when word gets out.
Hello All, I am a beginner to MSP430G2553, however all I am trying to do is get the MSP430 to execute the blink code while on 1.8V power supply. I have tried it on the launchpad board and it seems to stop working around 2.1V power supply. I then tried the barebones method by only using a bypass capacitor, pull up resistor for reset, and LED/current limiting resistor on a breadboard, but it seems that again the circuit only works down to around 2.0V. I measured the output pin while at 1.8V and it is in 10's of mV so it is not a problem of the LED getting degraded voltage levels but the fact that its barely getting any voltage. Is there something special I need to set on the chip before using this at 1.8V? Thank you for your time!
