We have shown how you can power mikroMMB for dsPIC33 board with a single 1.5V battery. Since Battery Boost Board drains a lot of current while generating 3,7V from 1,5V, we advised you to use two 1,5V batteries for stable and longer operation. We have tested this for you and we are very pleased with results. Running “Bouncing Boxes” example, batteries endured for 6h 20mins. This is just awesome! Imagine what you can do with 6h of autonomous power supply with this amazing board. Of course, this value may vary depending on your program and used external modules, and graphical content on TFT.
