2 PCS DC-DC MT3608 Step-up Power Supply Module Adjustable Boost Converter Input 2V-24V to 5V-28V 2A

Product Information

Nice touch, a limitation: as mentioned, it introduces a voltage drop of 0.65 V (or so). This voltage drop is current dependent, so you can’t really regulate this away easily using the variable resistor.

Not only that, it would also be a most-excellent thing to also see a basic "schematic" of this module using the same sorta software, like the free to use CADsoft Eagle, or when it used to be, i cant remember now as im old, lol

MANY other softwares out there for making one's own PCB's (which i would NEVER charge anyone to help make their own PCB's, after all, its just the board designs of simple modules so if one ever wants a hand in doing so, lemmi know !!) Před prvním použitím je tedy nutné použít vstupní napětí 2Va nastavit požadované výstupní napětí. Potom lze na vstup připojit zamýšlené nižší vstupní napětí. Specifikace:

The amount of busted modules ive got over the years ive started to buy the SMD individual parts so i can swap them out as the most important part of the module is the PCB itself. And much harder to make for folks just getting into electronics and electrical engineering :) It would have been nice to have a picture of the schematic embedded within the article, that makes discussing it much easier. Here is the TP4056 Datasheet. Here is the MT3608 Datasheet. We are not going in to details of TP4056 (which is a charger circuit) and MT3608 (which is a DC-DC boost converter). The datasheets will give you a fair idea that the end output voltage will be regulated and linear. Vyvarujte se stavu kdy je na vstupních svorkách vyšší napětí než nastavené na výstupních! Může dojít k poškození měniče! The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3608 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal soft-start results in small inrush current and extends battery life.MT3608 step up booster converter module is a small sized highly efficient and low cost module is built for converting or boosting the voltage as low as 2V to max 28V DC with the maximum output current of 2 ampere. The output voltage can be adjusted with the variable resistor used in the module. Because you have moved the current resistor _before_ the voltage regulation network, once the regulator is turned on, the output voltage will be exactly where you want it. Explicitly said: the current regulation network will see a lowered voltage because of your added resistor and will increase the output to compensate for the voltage drop caused by it. That’s its job.
