If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time.
This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.
The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.

Programming microprocessors such as ARM, AVR, etc
Working with computing hardware such as routers and switches
Serial communication with many devices such as GPS devices
Serial terminals on devices like the Raspberry Pi
Unlike most USB to TTL serial adapters, this adapter supports both 5V AND 3.3V operation! Simply set the jumper as required to choose between 5V and 3.3V as labelled on the board.
The adapter comes with a right-angle connector fitted allowing you to use it straight away. If you need to access any of the other inputs or outputs of the FT232RL, all the useful signals are provided as through-hole solder pads - ideal for use with straight headers into a breadboard, for example.

UBEC's (Universal Battery Eliminator Circuit's) are simply DC to DC step down voltage regulators! This UBEC is perfect for the Raspberry Pi, as it's able to take high voltages (5.5V up to 26V), and outputs a consistent safe voltage of 5V at up to 3A nominal or 5A max! The Hobbywing 5V 3A UBEC is a switch-mode type, which results in it being much more efficient than linear type UBEC's (so your batteries will last longer!)
UBEC's are perfect for applications where you plan to use the Raspberry Pi in a circuit with high voltages such as robots where you'll be driving motors!
Due to the voltage drop caused by the Raspberry Pi, it is recommended to input a minimum of 6.5V to receive a stable 5V output. Anything lower than 6.5V will result in a low voltage warning on the Pi.
Please Note. The Hobbywing UBEC can be set to output either 5V or 6V using an onboard jumper select! Please DOUBLE CHECK your output voltage is correct before connecting your microcontroller or circuit!
Features
- Designed with an advanced switch mode DC-DC regulator IC.
- Battery polarity reversal protection.
- A metal shield covers almost all the electronic components, and a specially made filter is attached to the output wires to significantly reduce the electromagnetic interference.
- The working status is shown by an indicator (LED), which lights when the output is in normal range.
- Output Voltage: [email protected] or [email protected] (Changeable with an output-voltage select jumper)
