It is engineered to sit flush along one side of a standard electronic breadboard. This single-sided module takes a high-voltage input (from an AC\/DC wall adapter or battery pack) and steps it down to steady, selectable micro-electronic logic rails (3.3V or 5V), turning on or off synchronously via a single master toggle switch. It is ideal for small-scale, lower-current circuits that require power along a single edge of the prototyping layout.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-NEhMdRXQGoolDmxIWTPlOom2gBR\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-BM6vdNzLconMMGxy3KClkzvNgip\"\u003eThe \u003cstrong\u003eXD-42\u003c\/strong\u003e is an advanced, high-efficiency gate-style or U-shaped power regulation module built on a clean white PCB substrate. Unlike standard single-side models, the XD-42 straddles the entire width of a standard 830-point MB102 breadboard, clipping securely onto both the upper and lower power rails simultaneously. Featuring two completely isolated, independently switched voltage channels, it allows you to run 3.3V on one side of your breadboard and 5V on the other at the same time. Its hollow center leaves the central breadboard tie-points completely unobstructed for clutter-free wiring.\u003c\/div\u003e\n\u003cp class=\"heading-2 ace-line old-record-id-HXw9dfHLMoQvKBx1RcMla11cgG2\"\u003e \u003c\/p\u003e\n\u003ch2 class=\"heading-2 ace-line old-record-id-HXw9dfHLMoQvKBx1RcMla11cgG2\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch3 class=\"heading-3 ace-line old-record-id-I0yldQa6OowUymxEAMylkCixg8c\"\u003e\u003cstrong\u003eMB102 — Single-Rail Profile\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul start=\"1\" class=\"list-bullet1\"\u003e\n\u003cli class=\"ace-line ace-line old-record-id-Q5Q7dC8eioncIVxhGOIlHjDogHb\"\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSingle-Edge Footprint:\u003c\/strong\u003e Occupies only one long edge power rail column of the breadboard, leaving the opposite side completely isolated for alternative battery sources or separate signal ground loops.\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-EzgHdul8BojvhcxfJb3lrMwSgNu\"\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSynchronized Master Shutoff:\u003c\/strong\u003e A single on\/off button manages both output pins simultaneously for simple, unified circuit cut-offs.\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-Fc8jdTK2xoQBp5x3EPMlVxtJgWc\"\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eDedicated USB-A Power Output:\u003c\/strong\u003e The onboard Type-A USB socket acts as a dedicated output tap, allowing you to run a secondary power cable out to an external microcontroller (like an Arduino Uno or NodeMCU).\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"heading-3 ace-line old-record-id-FogLdqsaJoBDFexGSXhlSvBcgrg\"\u003e \u003c\/p\u003e\n\u003ch3 class=\"heading-3 ace-line old-record-id-FogLdqsaJoBDFexGSXhlSvBcgrg\"\u003e\u003cstrong\u003eXD-42 — Dual-Rail Profile\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul start=\"1\" class=\"list-bullet1\"\u003e\n\u003cli class=\"ace-line ace-line old-record-id-XArmdG7RdowNeRxPgoKlTDhfgdb\"\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eDual-Channel Independence:\u003c\/strong\u003e Equipped with two separate toggle switches to independently control power to the left and right rails.\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-LRfLdOX8OoVDGyxc90TlzTHMg0b\"\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eMixed-Voltage Flexibility:\u003c\/strong\u003e Enables independent voltage selection (3.3V or 5V) for each rail, allowing you to power low-voltage 3.3V sensors and 5V microcontrollers or relays on the same board without cross-talk.\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-Y0ckdibxOoO6glxgeSklxdH3gWb\"\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBi-Directional USB-A Port:\u003c\/strong\u003e The onboard USB-A port is bi-directional;
