Recommended power requirement for Adafruit Huzzah CC3000 Wif

Post by oceanmono »

Hi, what is the recommended voltage and current to run this breakout? Is it recommended to use a dedicated battery source for it?

The CC3000 is a 3.3v device, and its peak current when transmitting is about 350mA. You can power it from an Arduino's 5v pin, or use a LiPo.

But my Arduino is powered using the usb port of the computer. According to your website, the current is not high enough.

A standard USB connection can supply 500mA, and an Arduino Uno uses maybe 50mA. Combined with the CC3000, you're looking at a worst-case load of around 400mA.

We've run CC3000 breakouts and shields from Arduinos powered by a computer USB connection lots of times, so it should work for you too.

If you have other things connected to the Arduino that use more current than a USB connection can provide, you can connect an external power supply to the Arduino's DC barrel jack. The Uno's voltage regulator can handle up to 1A.
