SparkFun 5V Step-Up Breakout - NCP1402 - PRT-10968 - SparkFun Electronics

The NCP1402 is a 5V DC-DC converter. This breakout board will accept voltage inputs between 1 and 4 Volts and output a constant, low ripple 5V output capab

Key Features Simple breadboard power supply Selectable 5V or 3.3V regulated voltage ON/OFF switch Power status LED 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 inch pitch for simple insertion into a breadboard. Input power can be supplied to either the DC barrel jack or the two pin header labeled + and -. Output power is supplied to the pins labeled GND and VCC.

PRT-10255: The LiPower board is based on the incredibly versatile TPS61200 boost converter. The board is configured to be used with a LiPo battery, has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V. However, the board can also be used as a general purpose buck and boost regulator with an input voltage as low as 0.3V (default UVLO is 2.6V).

NCP1402-5V Step-Up Breakout (Sparkfun PRT-10968)

BOB-16784: Do you have too many sensors with the same I2C address? Put them on the SparkFun Qwiic Mux Breakout to get them all talking on the same bus! The Qwiic Mux Breakout enables communication with multiple I2C devices that have the same address that makes it simple to interface with. The Qwiic Mux also has eight configurable addresses of its own, allowing for up to 64 I2C buses on a connection.

NCP1400-5V Step-Up Breakout - PRT-08999 - SparkFun Electronics

BOB-09370: 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 1.34kÎ resistor, or to get 3.3V use a 2.182kÎ. See table 1 in the module's datasheet for more resistor values.
