  • Breadboard Power Supply 5V/3.3V
    INTRODUCTION This is a very simple board that takes a 6-12V input voltage and outputs a selectable 5V or 3.3V regulated voltage. All headers are 0.1" pitch for simple insertion into a breadboard. It can be either powered from 6-12 DC2.1 power jack or from USB power.  The maximum current it can provide is 500mA.  SPECIFICATION Input voltage: 6-12V (Power Jack) 5V (USB) Output voltage:3.3V/5V Output current:500mA On/Off switch Power status LED Pin Head 5/3.3V output Central positive DC2.1 power jack   DOCUMENTS ..

  • DC-DC boost converter
    INTRODUCTION This is multipurpose boost converter, a breakout board. Supply voltage is as low as 3.7v and it boosts to as high as 34v.  With this module, you can now power your Arduino with our 3.7V lipo battery or use it to regulate any other project. The tiny form factor and its simplicty makes it for a very nice addition for all projects requiring an extra power module. Note: This board does not have reverse polarity protection, so please be sure to recognize the polarity of your connections! The input voltage must be less than output voltage, otherwise, it may damage the board. SPECIFICATION   ..

  • DC-DC Power Module 25W
    INTRODUCTION This Power Module is a small size 5A 350KHz 25V Buck DC to DC Converter. It can convert any DC voltage between 3.6V-25V to a selectable voltage from 3.3V to 25V. You can choose 5V direct output voltage with the convenient on-board switch or adjust the output voltage by the blue & white resistor. Three different output interfaces for convenient and fast prototyping of projects with multiple voltage requirements.The Ovout (Original Voltage output) interface can output the power supply voltage of input so that can be used to power other parts as well. This interface proves very helpful when using a power supply that fits the requirements for one component, and then use the power module to adap..
