5pcs dc-dc 12v 5v à 3.3v step down régulateur de tension module de puissance
Une partie de la critique a été traduite automatiquement.
Рабочая частота преобразователя около 340 Кгц, для fpv лучше не использовать. смог выжать максимум 2.45 Ампера. у некоторых экземпляров (двух из пяти) на входе и выходе отсутствуют блокировочные конденсаторы.
petit module tres petit ! pas tester encore mais ça ne serait tarder !!
I find this to be a rock solid stable voltage converter. I use these to power my receiver from my transmitter reliably so that I can update the firmware on the receiver. Wiring is straight forward and when you test the output it 3.3V as it should be.
Very good and fast. Perfect for my purposes. I have tried it and it complies with all its characteristics. With 4 v. of entry, already has the output of 3.3v.
O produto cumpre o que promete, recomendo a todos.
they use the MP2307 3A, 23V, 340kHz Synchronous Rectified Step-Down Converter
contento funciona perfecto. usado fpv tambien cualquiera
This step-down is very useful if you with to step down the voltage for an AIO FPV camera when you would like to have it connected to a battery with a voltage higher than 3.3
to be tested
but not too small, everything works great
