jOY-it RB-LLC Logic Level Converter 3.3/5V for Raspberry Pi

jOY-it RB-LLC Logic Level Converter – 3.3/5V Voltage Level Shifting for Raspberry Pi GPIO

The jOY-it RB-LLC Logic Level Converter enables safe connection of 3.3V and 5V components to the Raspberry Pi. It bidirectionally converts voltage levels and protects sensitive GPIO pins from overvoltage.

• Bidirectional level shifting between 3.3V and 5V – ideal for sensors and actuators with different logic voltages
• 40-pin GPIO compatible – direct connection to the Raspberry Pi without additional breadboard
• Compact design – fits any breadboard and saves space on the workbench
• Easy to use – no external components required, plug and play

What sets the RB-LLC apart

Unlike simple voltage dividers, the RB-LLC operates bidirectionally and is therefore suitable for I²C, SPI and UART communication. The output voltages of 3.3 and 5 volts cover the most common logic levels and make it a universal tool for any maker project.

Ideal for...

The RB-LLC is aimed at Raspberry Pi enthusiasts, hobbyists and developers who want to safely connect modules with different voltage levels. Whether temperature sensor, OLED display or motor control – with this converter the GPIO interface stays protected.

How to use the RB-LLC

Plug the converter directly onto the 40-pin GPIO header of the Raspberry Pi. Connect the 3.3V and 5V pins of your peripherals to the corresponding channels on the converter. Bidirectional operation requires no additional configuration – level shifting happens automatically.
