Power source for the Rastuino project.

This is the first prototype for the Rastuino power source.


The objetive is to provide a light power source for an Arduino incorporated to the Rasti blocks system.


I used a 18650 Li-ion cell (generic UltraFire rated 8800 mAh ... lets say around 2000 mAh real), a TP4056 USB charger and an MT3608 step-up converter.


The interruptor is used to avoid fully discharging the battery while not in use.


The plug is an 2.5 mm plug used for Arduino power sources.


The charger and the step-up are cheaper than a battery cell.


This module can repleace 6 NiMH, usually used for this purpose.
