Our BitsyXb is going to be paired with an external radio. This radio takes 5v and up to 3A (Although I have never seen it go over .5A, and question the high amperage) We would like to power the radio from one of the 5v sources on the Bitsy, but I am not sure what would be the best place to get it from. One other requirement is to be able to shut down the power to it. I was thinking the LCD power, since we will not have a screen, and you can shut it off?
This could possibly be done; however we have a limiting switch to 1A. Can you please email us directly to support.us@eurotech.com to see how we can best support you with your application needs.
