It is commonly used with Arduino boards (Uno, Mega, Nano via Vin) that have an onboard regulator stepping down to 5V. For Raspberry Pi, a separate 12V-to-5V step-down converter is required. Always verify your device’s voltage and current requirements before connecting.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003ePlug the DC barrel jack into your board’s power input—center positive is the standard for most development kits. Avoid drawing more than 1A continuously to prevent overheating or voltage drop. When powering inductive loads like motors, adding a 100µF electrolytic capacitor across the output can help stabilize the supply.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.

The board’s voltage regulator safely converts 12V to 5V for the microcontroller.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use this to power a Raspberry Pi?\u003c\/summary\u003e\u003cp\u003eRaspberry Pi requires a 5V supply, so you will need a step-down converter to reduce the 12V output to 5V. This PSU can then serve as the primary source for the converter.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the connector size?\u003c\/summary\u003e\u003cp\u003eThe DC connector has a 5.5mm outer diameter and 2.1mm inner diameter, with center positive polarity. This is the standard size used by most Arduino boards and common development kits.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
