Do you fear that your power may not be "far reaching" enough? How would another 3' work for you? Okay, so it doesn't sound very dramatic, but sometimes an extra 3' of power cable is exactly what your project needs. Don't hack apart a nice clean barrel jack connection just because it won't reach, this male-to-female barrel jack extension cable will make the reach. This cable is terminated with 5.5x2.1mm barrel connectors, one male and one female, and fits most of our products that use a DC...

This is an industrial grade DC Buck-Boost converter that inputs 8V to 36V and outputs 12V up to 6A or 72W. With plenty of heatsinking and protection, this DC block is perfect for battery applications (such as SLAs or LFPs) that need to power a steady load (such as 12V router and WiFi equipment) even while the input is varying (battery charge/discharge). 94.2% efficiency makes this a good, plug and play, DC Step-Up/Down solution. Features: Input Voltage: 8 to 36VDC Input Current: 11A DC...

The MI:power board for the BBC micro:bit brings real portability to your wearable projects. The stylish, lightweight PCB is designed to fit snugly against the BBC micro:bit and features a built-in buzzer and 3V coin cell holder. This latest version has been redesigned to fit both the V1 and V2 micro:bit. When assembled, the MI:power board is connected directly to the 3V, GND and P0 connections on the micro:bit. The 3V and GND connections provide power to the micro:bit and the built-in buzzer...

Who doesn't occasionally need power regulation? We certainly do, so we've designed the SparkFun BabyBuck Regulator Breakout to help us with just such a task. Featuring the AP63203 from Diodes Inc, this breakout board takes advantage of a 2A synchronous buck converter that has a wide input voltage range of 3.8V to 32V and fully integrated 125mΩ high-side power MOSFET/68mΩ lowside power MOSFET to provide high-efficiency step-down DC/DC conversion. All of this snuggled up in a low-profile, TSOT26...

The SparkFun Buck-Boost Converter is a handy power accessory board that allows you to fine tune the amount of power your project receives. This converter can take an input voltage of anywhere from 3-16V which can then be regulated to an output voltage between 2.5-9V. With the switch on the bottom of the board, you can set the common output voltages of 3.3V and 5V, but we've also added a custom setting that allows you to solder a resistor based on your custom voltage needs. The GPIO pins have...

This is a breakout board for our non-isolated, 6A DC-to-DC Converter Module. The module can convert any DC voltage between 4.5-14VDC to a selectable voltage between 0.59 and 5.5VDC. To set the output voltage to the desired level, a resistor must be added between the Trim and GND pins. For example, to set the module to output 5V use a 1.34kΩ resistor, or to get 3.3V use a 2.182kΩ. See table 1 in the module's datasheet for more resistor values. The ON/OFF pin on the board can be pulled high to...

This breakout board uses the LTC3588 Piezoelectric Energy Harvester from Linear Technologies. This board can be used not only for harvesting piezoelectric energy, but solar energy as well. There is a bridge rectified input for piezo elements (PZ1 and PZ2) and a direct input (VIN) for DC sources. Both are clamped to 20V. In addition, the board can simply be used as a standalone nanopower buck regulator. An ultralow quiescent current undervoltage lockout (UVLO) mode with a wide hysteresis window...

MOSFETs are awesome. They're like a switch that you flip electronically! This SparkFun MOSFET Power Controller makes it easy to switch a battery supply on and off using your favorite microcontroller. The board also has sewable pads so you can use it in e-textile projects that need more juice. The MOSFET Power Controller came about because microcontrollers, like the Arduino or LilyPad Arduino, can only supply a limited amount of current. Sometimes, though, you want to control something that...

Sometimes we want our projects on, but sometimes we want to turn them off for a while to save power. The SparkFun Nano Power Timer will run while only consuming minimal power (approximately 35nA) and turn your project on after a set amount of time. When you are done polling your sensors, posting data to the web, writing to your logger, or planning world domination, your microcontroller can tell the Nano Power Timer to turn off the power. No more running your microcontroller all day when you...

It's time to effectively manage the power distribution into your project and with the SparkFun Power Delivery Board, you can! Traditional power adapters can provide a wide range of current but the voltage stays fixed at 5V. With the SparkFun Power Delivery Board's USB-C connection it has the ability to achieve higher voltages, typically 5-20V and up to 100W of power. The Power Delivery Board uses a standalone controller to negotiate with the power adapters and have them switch to a higher...
