bPiShift is a plug-and-play voltage level shifter that connects directly to the 40-pin GPIO header on your Raspberry Pi. Its small, unobtrusive footprint lets it slot in without blocking critical Pi functions and ports.

Whether you’re prototyping with 5 V sensors, serial devices, or microcontrollers, bPiShift provides a reliable and clutter-free way to safely interface with 3.3 V GPIOs—no jumper wires, no external boards, and no risk of damage.

Shift Your Expectations

Thoughtfully designed, bPiShift offers a number of features that help it stand out from competing solutions.

• Direct GPIO Header Interface: bPiShift plugs directly into the Raspberry Pi’s 40-pin header, providing a compact, solderless level-shifting solution without additional wiring.

• Bidirectional Logic Level Shifting: Supports safe bidirectional voltage translation between 3.3 V (Raspberry Pi GPIO) and 5 V logic devices using proven MOSFET-based circuitry.

• Compatibility & Form Factor: Designed and tested for Pi 2/3/4/5 and Zero series, the small form factor maintains access to GPIO and fits within most standard Pi enclosures.

Tested for Compatibility

The bPiShift has been validated on Pi 2/3/4/5 and Zero models. It has been tested with serial devices, I²C peripherals, and logic-level sensors, ensuring reliable compatibility and performance.

Features & Specifications

• 5 V level shifting on all 28 usable pins of the Pi-type 40-pin header
• Selectable 5 V power source jumper
  • Use onboard or a separate external power supply
• Laser-etched pin labels for easy identification
• Power indicator LED

Open Source

The bPiShift is open hardware. While development is still ongoing, all hardware files (Schematic & Gerbers) will be published on our GitHub under a standard open-source license before we ship to backers.
