Add power supply to your prototypes
This power supply designed for breadboard prototyping directly takes power from DC wall wart and outputs a selectable 5V or 3.3V regulated voltage.
This DC/DC step-down voltage converter is based on MP2037, it converts input voltage between 4.5V and 23V into a smaller voltage between 1V and 17V, capable of driving a 1.8A load with excellent line and load regulation.
Sparkfun Servo trigger is a small board that can control movements of servo motors.
AttoPilot Voltage and Current Sense Breakout - 180A is used to monitor the voltage and current sense.
This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel 1 mOhm shunt resistors, then converted to a final analog voltage output by the TI INA-169. Voltage sense is accomplished by scaling to 3.3V ADC range by a precision resistor divider.
This current sensor gives precise current measurement for both AC and DC signals.
This is our version of the OpenServo open-source servo controller board. It's meant to replace the existing controller board in any standard servo (~.78 inch servo width).
Sparkfun Babysitter is an all in one solution to keep you project powered up for an extensive period.
SparkFun Power Cell - LiPo Charger/Booster boosts up your battery power, comes with two separate connectors and output pins.
This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals.
This is the Sunny Buddy, a maximum power point tracking (MPPT) solar charger for single-cell LiPo batteries.
