  • Pololu

    Pololu is an electronics manufacturer and online retailer serving education, maker, and professional engineering industries with products ranging from sensors and motion control electronics to motors and wheels to complete robots. We strive to offer well-engineered, quality products that enable our customers to take their own projects from idea to reality. Here is why you can rely on Pololu: Good people It takes good people to make good things. Pololu has a world-class team with shared values, which allows us to seek the right way to do things together as well as to help each other improve. That leads directly to better products and a better customer experience. Pololu electronics manufacturing area with multiple pick and place lines. We make our products We manufacture most of the products we sell. Because we control everything from initial design through manufacturing, testing, and packaging, we can offer unique products quickly and economically. We are constantly improving our processes to bring you better parts at lower prices. Thermal image of the top side of the dual VNH5019 motor driver shield during one of our current tests. Quality engineering The engineering of our products differentiates Pololu from the competition. We take a rigorous approach to the details of every product, from design, to validation, to evaluating feedback from customers. Commitment to support At Pololu, we are committed to standing behind our products with a full spectrum of support, from complete documentation (including high-quality pictures, connection diagrams, schematics, datasheets, and example code), to maintaining stock levels so that you can buy the parts you need, to providing same-day shipping service so that you can get your parts as quickly as possible. If you have trouble with a product, you can call, email, or post on our forum and receive help from real engineers. Company background Pololu was founded in 2000 by three students at the Massachusetts Institute of Technology. Our first product was the unique IR beacon system developed for the 6.270 Autonomous Robot Design Competition. The beacons allowed pairs of robots to detect each other, allowing MIT students to give their robots more sophisticated strategies. In 2001, Pololu was incorporated while still operating out of an MIT dorm. Upon graduation of the last founder in 2002, we moved from Massachusetts to Las Vegas, NV for its better climate and lower taxes. Our office has since become the meeting place for the Las Vegas robotics club, which was formed in 2004.

  • OPIS

    The compact (0.32”×0.515”) U3V12F5 switching step-up (or boost) voltage regulator takes an input voltage as low as 2.5 V and efficiently boosts it to 5 V.
    The pins have a 0.1” spacing, making this board compatible with standard solderless breadboards and perfboards.

    Overview

    These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.5 V.
    They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters)
    and have a typical efficiency between 80% to 90%.
    The available output current is a function of the input voltage, output voltage, and efficiency (see Typical Efficiency and Output Current section below),
    but the input current can typically be as high as 1.4 A. This regulator is available with a fixed 5 V, 9 V, or 12 V output:
