Nice step up converter! Output voltage is 31V max. Output ripple (5V in, 24V 0.1A out): 0.3Vtt. Efficiency: 70%.

These little boards loosen your hands and I think they should be in every amateur electronics. Price that does not even need discussion. Αυτά τα μικρά πλακετακια σου λύνουν τα χέρια και θεωρώ πως πρέπει να υπάρχουν σε κάθε ερασιτέχνη ηλεκτρονικό. Τιμή που δεν χρειάζεται καν συζήτηση.

Fonctionne comme prévu. Attention, ce module produit de la CHALEUR!!

Works as expected. Be careful this module produces HEAT !!

I am experimenting with these boards to put multiple windings on. According to the datasheet for the LM2587 this can be done ( using different toroids from my junk box.). I hope to use these switchers and boards to provide the multiple voltages needed to power a small CRT (see photo).

Beware the underside will short out if on a conductive surface. Will need ventilation to keep cool when used near max-output.

I intend to use a few 18650 batteries to drive this outputting 5V required to operated the BIKIGHT 3000LM Waterproof T6 USB Power LED Bicycle Front Light... on my motorized bike. The T6 light requires 2A @ 5vdc. The LM2587S is limited to 5A output but will do this job nicely. Thank You !

C'est un produit approprié. Produit de performance de prix. Et ça marche bien. Le délai de livraison est rapide.

It is a suitable product. Price performance product. And it works well. Delivery time is fast.

Arrivé en avance sur l'heure prévue! Bravo Bangood ! Je ne peux pas dire si ça marche bien, je n'ai pas le temps de l'essayer. Comme d'habitude, pas de dépliants ou d'instructions... dommage.

Arrivato prima del tempo previsto! Bravi di Bangood! Non posso dire se funziona bene , non ho tempo ora per provarlo. Come di solito, nessun foglietto o istruzioni... peccato.
