I want to use pololu step-up converter https://www.pololu.com/product/2836 in order to power a 5V device with two Ni-Mh batteries (1.3V each). It has only Vin, Vout and GND connectors. I've checked with voltmeter the batteries together and they give stable 2.6V, which should be, according to specs of the converter, enough to make it work.
I've tried wiring as below
I don't know what am I doing wrong... Is this wiring wrong or my converter broken?
