DC-DC Boost Converter MT3608 Review

In general, for such a price, it is better not to take it, since the marriage, as a result, is short on the chip. How is it determined: if you turn the knob, and the voltage stands still, and the input and output readings differ by 10%, then the chip is 100%. When it does, it turns off.

I checked it late, already when assembling the circuit, now there is no point in arguing with the seller, Ali has the same modules with the same chance of working.

After reading the comments, I did not believe that the goods could come not working. Finally, it doesn't work! No matter how much I twist it, the voltage does not change :(

The tuning cut works quite cunningly, it does not increase the first 5-10 revolutions at all, and many complain that the board is defective, you just need to turn it further, and there will already be an increase. Also, do not forget that the input current should not exceed 1.5 -2A Different pros: Simplicity and minimalism, of course, there are similar scarves and smaller ones, but these are good for their cheapness (especially when buying from a manufacturer). the generator starts up from 2 v,

I took a vacuum cleaner for a robot, since the purchased fan motor pulled very weakly at 7.3 Volts. With this converter, I raised the voltage to 13 Volts, and the thrust appeared. The output current is 100 mA, the circuit does not heat up. When you first turned it on, it was from 7 to 17 Volts, it’s good that it was connected to a ballast resistor. A multi-turn resistor clockwise reduces the output voltage.
