Ja uporan sa strujom na mom Apn4.
Evo surfajuci po Aliexpresu mislim da sam nasao resenje za struju na Apn4 6v/17w napajanju, i to veoma jeftino.
Treba mi misljenje nekog ko se vise razume u struju.
Narucio sam ovaj modul. Plan je da ispravim struju prvo, da dobijem DC na nekih 5-6 volti
LM2596HV AC/DC to DC Buck Step Down Converter Adjustable Step-Down 3A Power Supply
ovo su njegove karakteristike:
Electrical Parameters:
Input voltage range: AC 5V-30V, DC 5V-50V
Output output range: DC 3.3V-33V
Output current range: up to 2.2A (the regulator chip can withstand a maximum current of 3A, can work at 3A output current for a short time
Module size: 51mm*26mm
A onda ako taj napon ne bude bio stabilan (a nece), da sve to stabilizujem (cak i boostam) na 6v DC sa ovim modulom:
5A DC-DC Step Up Power Module Boost Volt Converter 3.3V-35V To 5V 6V 9V 12V 24V
