for tinkering with lipos 1 s
To be honest, didn't try it yet, but I believe that's good, while looking at good quality pcb. 1.30e per piece is really ok price.
These seem well built and preform as described however 1.5 amp is about the limit. At 1+ amp draw they get hot.....to hot to touch! I mounted several modules to an aluminum heat sink which made them run much cooler and they will likely last much longer. Great product just beware of its limitations.
great
Very fast delivery that step-down module does what it's supposed to do.
OK.
Works fine, lacks ready for it
Good product, excellent for battery operated applications that require usb power as well. Output is stable 5v, no hum or ripple so all good.
Small and good quality
very good
