Calling all electronics tinkerers and DIY enthusiasts! This set of 10 LM317 adjustable voltage regulator modules is a must-have for your projects. These little boards are linear regulators that let you step down DC voltage smoothly. Input can be anywhere from 4.2V up to 40V, and you can adjust the output from 1.2V to 37V—super flexible for different needs. They handle up to 2.2A typical output current (1.5A minimum), so they’re great for powering sensors, LEDs, small motors, and more. The max output current depends on your input-output voltage difference, but it’s solid for most hobbyist uses. Each module is compact at 35.6mm x 16.8mm and can handle temps from -55°C to +150°C. Easy to hook up: VIN and GND for input, VOUT and GND for output. Perfect for breadboarding, prototyping, or fixing up power supplies. Whether you're building a lab bench supply or tweaking an existing circuit, these reliable LM317 boards have got you covered. Grab a pack and start creating!
