  • Thank you very much for your prompt help and advice to a novice in this field, this is greatly appreciated! Cheers from the Swiss Alps Juerg

  • Hello I am using a big easy driver with an arduino uno for a dolly project. Everything works fine with a regulated power supply 12V/2.2A for the BED and USB power for the Arduino. Now, I would like to use a single 3s Lipo, 11.1V/2200mAh, to power everything. What are my best options? The BED’s Vcc 5V output appears to be just below Arduino’s power specs. Powering the Arduino with the LiPo directly might be just above the recommended specs and a lot of battery power will end up in heat, as a charged Lipo supplies 12.6V.

    Thanks for your advice.

No public wish lists :(
