Hi Everyone,
I recently bought a number of very small DC-DC stepdown modules
Normally these modules have 4 connectors: In+/In- and Out+/Out-
This one does have four connectors, labeled as
VO+, GND, -IN+ and EN
Does anyone know what the EN stands for and how I should connect this module?
Thanks!
EN stands for enable, you need a high on it to turn it on. Check your module can be anywhere from 3-5v depending on how it's set up.
Usually EN inputs have a pullup resistor, so you ground them to turn the output OFF. Otherwise leave it unconnected.
VO+ = volt out +
GND = shared for volt in and out
IN+ = volt in +
