It plugs directly into the breadboard's power rails via its red (+) and blue (−) pins, eliminating the need for extra jumper wires to supply power.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use a USB power bank or phone charger to power the MB-102 module?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The Micro USB input accepts any standard 5V USB power source — including USB wall chargers, power banks, and computer USB ports. This makes it extremely versatile for both desktop prototyping and portable project setups.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I select between 5V and 3.3V output on the MB-102?\u003c\/h4\u003e\n\u003cp\u003eA: Each of the two output rails has an onboard jumper that lets you independently select 5V or 3.3V output. Simply move the jumper to the desired position for each rail before powering on your circuit. This dual-rail configuration lets you simultaneously power 5V and 3.3V components from the same module.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What breadboards is the MB-102 Power Supply Module compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The MB-102 Breadboard Power Supply Module is designed to fit standard MB-102 breadboards, including common 830-point and 400-point versions.
