acheté pour booster l'alimentation d'enceintes nomades Bluetooth avec deux 18650, brancher multimètre sur Vin+/Vin- puis tourner la petite vis pour afficher le volage souhaité, le module est très petit et prend peu de places.

This is the module powering my DSO Shell oscilloscope at about 9.5V from an 18650 cell. It shows about 10-15mV ripple at around 10kHz(?).

If anyone has any problems with these boost converters most of the time they're not broken you just have to turn the trim pot up to 20 times in the anticlockwise direction until the voltage starts to climb. I thought all of mine were dead until I did that. Apart from that they're good value little modules.
