Good product, output voltage spot on 3.3v, it is tiny, and good price. Recommend use it to drive low current circuit, like ESP01
constant current
small useful converter
Just as described
great
ALL OK
Good value
I'm happy with it - is working as described. I'm used it as 2x AA battery replacement in wireless roomstat
very small, so easy to integrate without taking space
Zu hoher Eigenverbrauch, um Li-Ion-Akkus auf 3.3V zu stabilisieren. Akkus sind zu schnell leer.
