Most of smd components are pre-soldered except electrolytic caps and IC´s. if you are
experiencing bad behavior from the module, they´re high probabilities that IC´s are not
properly soldered to the board. Follow the next instructions to solve any issues.
1. Check polarity of IC´s.
2. Check if there is a short by measuring continuity from the positive/ground,
negative/ground and negative/positive.
3. Check if IC´s are fed with - and + voltages.
