Kit d'Alimentation 5/3,3 V pour Planche à Essais Sans Soudure SFE

Fits the breadboard and really easy to assembly even for beginners in electronics (as I am). Reliable so far.

This circuit is easy to build, but since it does not come with a build sheet; besides soldering experience you should have access to resistor color code information (for correct placement of resistors). The only other component that is tricky to place is the Power LED which must be installed in the correct orientation (not marked like electrolytic caps; lead length is the clue). You best test the LED to determine the + pin orientation before soldering in place. I also found the output voltages to be 3.21 (for 3.3 setting) and 4.88v (for 5V setting). The last comment is that the breadboard pins are in line on the circuit board, but when you plug into the solderless breadboard the power bus lines are offset slightly which means the power supply board does not sit square on the breadboard (not a big issue just an observation). It would have been nice if the circuit board offset the breadboard output pins to match the breadboard.

Ce circuit est facile à construire, mais comme il n’est pas accompagné d’une feuille de construction; en plus de l'expérience de la soudure, vous devez avoir accès aux informations du code de couleur des résistances (pour un placement correct des résistances). Le seul autre composant qui soit difficile à placer est le voyant d'alimentation qui doit être installé dans le bon sens (non marqué comme les capuchons électrolytiques; la longueur de fil est l'indice). Il est préférable de tester le voyant pour déterminer l’orientation de la broche + avant de souder en place. J'ai aussi trouvé que les tensions de sortie étaient 3.21 (pour le réglage 3.3) et 4.88v (pour le réglage 5V). Le dernier commentaire est que les broches de la planche à pain sont alignées sur le circuit imprimé, mais lorsque vous branchez la carte à pain sans soudure, les lignes du bus d’alimentation sont légèrement décalées, une remarque). Cela aurait été bien si le circuit imprimé compensait les broches de sortie de la planche à pain pour correspondre à la planche à pain.

Works great, fairly simple to assemble as long as you can solder.
