I decided again to devote my article to problems with power supply. homemade and their solution using small and inexpensive modules. I think many will agree with me that this topic is quite relevant in our business. Imagine the situation you have collected electronic a device that should be powered by 5 V, but in your case there is either not enough space, or for any other reason you can only use a power source below 5 V, even some transistors may not open at low power, this is also the reason. So, a step-up module can help in solving this situation, but also of a rather small size to fit in the case. It is about such a module that will be discussed in our article.
This boost module can accept 2 to 5 V input and a maximum current of 2 A, the output voltage is 5 V.
The main advantage of this module is its size, it is really very small. I think this module will be appreciated by many electronic engineers, because it can be used in various miniature projects, for example, to make a flashlight or some other highlight on its basis, there are many options for use, it all depends on your imagination, skills and needs.
The cost of this module at the time of writing is 73 rubles, the price can constantly change, delivery is paid and costs about 10 rubles.
Well, thank you all for your attention and good luck in future projects, friends!
Cost: ~ 73
