AZDelivery Compatible with MB-102 Breadboard Power Supply Module 3.3V 5V 700mA Adapter for Solderless Breadboard MB102 compatible with Arduino Including E-Book!

Bought a three pack. On the top (near the USB port) has HW-131 written.Input power used 1) a 9V alkaline battery 2) 12.2V from bench supply.Checked the output voltages. The bottom PINS show the 3.3V or 5V volts (+- 0.01V) on either side depending on the jumper settings. The relevant PINS on the top (next to capacitor) are giving out both 5V and 3.3V (+- 0.01V) ( two pair PINS each) irrespective of the jumper settings.So all looking good. I haven't opend the other two from the three pack but based on the first am expecting they will work fine too.

Worked fine and has been useful for a number of projects. I use a 12V power supply. The voltages appear stable (OK - don't have a proper way to analyse that). Only thing I'd change is to add a spacer at the back - there's 2 rows of power pins to plug into the breadboard at the front with spacers (so the board sits 3 mm or so off the breadboard), but nothing at the back under the switch so it rocks back unless you hold it - or glue a couple of spacers on which did the trick.

Arrived via Amazon Prime next day as we now expect.Bought a 3 pack and haven't tested all 3 yet but first works fine.Fits perfectly onto standard breadboard with straight pins and clear markings on PCB.Downloadable PDF covers all you'd need although it is hardly rocket science.I've only tested jack plug (standard 2.1mm/5.5mm) via a 9V PP3 since the USB socket is one of those old big USB sockets and I didn't have a male to male cable at hand - a bit surprised with this.Locking push button to turn on/off power.Green LED lights when power on.Seems to use AMS1117 5.0/3.3 voltage regulators soldered direct to PCB.Looks like you can have 3.3V on one side and 5.0V on the other but not tested this.

To add more detail, it works for some of my components on battery power (liquid level sensor and PPM sensor) but not an HTU21D... absolutely bizarre issue. Especially since the datasheet says DO NOT POWER VIA USB, yet it only works properly via USB :DD amazing.Ok dropped to 1*, was having reliabiltiy issues seemingly due to a temp/humidity sensor. Switched the 3v3 supply from this BB power supply module to an ESP32's 3v3 out (also from AZdelivery) and the components works fine now, go figure :D

The surface mount stuff is fine.The hand soldered headers are at weird angles and poorly soldered.Usable, but not great.

at this price i thought it must come from the other side of the world on second class, but ABRA-C-DABRA it came in 2 days! (i can work with that) and these ones have an LED. as my old ones didnt!

Accurately made physically (no pin bending to make it fit) and electronically (all outputs within 10mV of stated value on a calibrated Fluke). All 5 units work perfectly. Excellent pre and post sales communication with AZDelivery. Unusual these days to get a top notch product for a bargain price.

These are excellent quality. I had originally brought a set of five from an alternative supplier, only to find that 2 of the units didn't work properly as the power switches didn't latch. No such trouble with these, all working properly.

Mycket bra lösning och hade fått en femma om inte AZDelivery försökt att sno min information genom att tvinga folk att registrera för att få något som alltid borde ingå obligatorisk, en manual. Jag menar det är inte ens fråga om en gammal hederlig pappermanual utan ettor och nollor. Sånt stör mig rejält då jag inte tycker att andra har rätt till min information.

Module bien utile pour alimentation planche de prototypage.

Arrivato intatto e perfettamente Funzionante.Ho atteso alcuni mesi per la Recensione di questo Dispositivo per accertarmi della sua Affidabilità nel tempo. Sono trascorsi più di 6 mesi, l'utilizzo è stato sporadico ma importante e non ho riscontrato anomalie.Le tensioni in Uscita misurate erano 3.3 V - 5 V, il Diodo Led spia di Alimentazione e il Micro Interruttore sono integri e funzionanti.Un Buon Acquisto.

Bastler ( Maker ) die mit Arduino usw. und Steckbrettern arbeiten werden das MB102 vermissen, wenn es mal defekt sein sollte.So etwas braucht man immer.Ein Kritikpunkt gibt es aber.Das MB102 hat keinen Schutz gegen zu hohe Eingangsspannung und Kurzschluß.

Bien conçu et fonctionnel !- parfaitement adapté aux breadboards.- on peut choisir 3,30V ou 5,00 V pour chacun des deux rails d'alimentation- interrupteur avec voyant led d'état de fonctionnement, c'est appréciable.- tensions précises (pour l'instant avec une faible charge)- un vieux bloc d'alim de 9 V, trouvé dans un tiroir, avec la bonne prise convient très bien. Se conformer à la fourchette de 7,5 à 12 V possible en entrée.- pins protégées par une mousse mais carton d'emballage un peu juste pour les 3 plaques...- très bon tarif par lot de 3 dans mon cas... car le prix varie souvent...- circuit imprimé pas très net...- pour la doc, il faut comprendre qu'il faut "l'acheter gratuitement" sur le site... ou la trouver par hasard sur le net... et il faut se contenter de l'anglais toujours rien en français !Ca vaut tout de même 5 étoiles !
