    handy little boards for when you need a higher voltage than the supply, just wish they had current regulation too, fitted with a current limiting resistor after the board is necessary otherwise they get very hot (170'c+) on the IC and Diode or use with banggood step down board with current regulation in this case making a 26V 1A charger from a 12V supply

    Very small and does what it says on the tin. It gets quite hot above 1A (no surprise there), but good value!

    Nice little step up module. 2-24v boost with a max output current of 2A. Always start with low voltage 2-5v and increase the pot. output voltage to +3-5v from where you want to have your steady input voltage at or it will burn up. Other than this little cork this is a great step up module for the price! Good for low current projects.

    Leider sind 5 Schaltungen von 10 Stck. nicht in Ordnung gewesen. Das Poti vor Beginn 20 Drehungen nach rechts drehen, dann zurück bis die gewählte Spannung am Ausgang anliegt, dann ggf. belasten. Messdaten bei Ue=10V, Ie<1,9A (Schaltfrequenz ca. 3MHz bei Ua=16V) RL=24 Ohm 1.) Ua= 16V --- Ia=674mA --- Pa=10,7W ----> i.O. 2.) Ua= 18V --- Ia=752mA --- Pa=13,5W ----> Zerstörung ohne zusätzlichen Mini-Kühlkörper Meine Empfehlung: Ausgangsleistung max. 10Watt
