A common rule of thumb for a 5V supply driving a standard 2V red or green 5mm LED at 20mA is a 150Ω–220Ω resistor. For 3.3V supplies, 100Ω–150Ω.

They take a data signal from a microcontroller and you can address each LED individually for color and brightness. Standard LEDs are passive, you wire each one and switch each one separately, or drive them in groups with a single MOSFET (a switching transistor).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\n\n\u003cbr\u003e\n\u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n\u003cp\u003e\u003cstrong itemprop=\"name\"\u003eWill these LEDs fit a Game Boy or retro console power-LED replacement?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\n\u003cp itemprop=\"text\"\u003e3mm through-hole LEDs are the typical replacement size for older Game Boy and console power indicators. SMD packages (like 0805 or 0603) are needed for board-level mods on more recent revisions. Check your console's existing LED footprint before ordering, through-hole and SMD are not interchangeable without rework.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","products":[],"url":"https:\/\/www.zedlabz.com\/en-eu\/collections\/leds.oembed","provider":"ZedLabz","version":"1.0","type":"link"}
