    I got one some time ago, i used it today. CONST: 1) Mine isn't a LM2577 but a XL6009E1. 2) The input voltage is 5v to 32v (page 5 of datasheet v 1.1) and not 3v to 30v. 3) The output voltage can go up to 60v and not to 35v, the output cap is 100uf 50v so it can explode. 4) The capacitor on the input (220uf 35v) is rotated and soldered by only the negative pin, the other on the positive isn't soldered. I'm not good with smd soldering so probably i'm gonna destroy it in the tentative of fix it... PRO: 1) Low price.

    Отличный преобразователь, греется в меру, лучше поставить радиатор на микросхему, работать начинает с 3 вольт, отличное решение для резервного зарядного, не убьет аккумулятор, т.к. перестанет работать разрядив его до 3 вольт, использую для поднятия напряжения до 12 вольт, отличное качество пайки, все прекрасно работает, спасибо Банггуд)))

    Pt-Br: Ele parece grande mas na mão é bem pequeno, versátil, fácil de instalar (vem com dois furos para fixação) bastando apenas soldar os fios e rotacionar, bom acabamento. Pra quem é hobbysta ou estudante, uma ótima opção para utilização deles em projetos que utilizem uma bateria (Pilha AA por exemplo) ou que necessitem de uma tensão maior que a fonte principal (Um backlight, um VFD e etc). No meu ponto de vista, foi uma ótima aquisição. Só antes de ligarem no projeto, regulem a tensão utilizando um multímetro, senão frita seus aparatos! Ah, ele veio superprotegido no pacote, enrolado em um plástico grosso!

    Использую его для повышения напряжения с 3,7в до 12в для питания камеры FPV. отличное решение, всем советую. Работает идеально

    good product, the output voltage regulation is very precise, and does not vary with the input voltage variation.A display indicating the output voltage directly on the module would be convenient.But for the paid price it is fine.
