Ensure your USB‑C PD charger can supply 3A at 5V; many phone chargers only deliver 2A, which may starve a Raspberry Pi under load. For single‑board computers, always power through the GPIO 5V pins—not the USB‑C port—to avoid back‑powering issues.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"faq\"\u003e\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003ch3\u003eCan I use this adapter to power my Arduino Uno via the barrel jack?\u003c\/h3\u003e\n    \u003cp\u003eNo, the Uno’s barrel jack input expects 7–12V; a 5V supply will not pass through the onboard regulator.
