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.

bPiShift provides a reliable and clutter-free solution for safely interfacing 3.3 V Raspberry Pi GPIOs with 5 V sensors, serial devices, or microcontrollers—eliminating the need for jumper wires, external boards, or risk of damage.

### Features

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 for all 28 usable GPIO pins.
* **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.
* **Power Selection Jumper:** Includes a selectable 5 V power source jumper—use either the onboard 5 V rail or a separate external power supply as needed.
* **User-Friendly Design:** Features laser-etched pin labels for easy identification and a power indicator LED for quick visual confirmation of operation.
