bPiShift is a snap-on 5 V logic level shifter for the Raspberry Pi’s 40-pin GPIO header. It connects to the PIs GPIO header with a female connector and provides a clutter-free interface for 5V devices such as sensors, serial modules, and microcontrollers, making it a compact solution for prototyping without jumper wires or extra boards.
The board supports bidirectional MOSFET-based level shifting across all 28 usable GPIO pins, with a 5 V power jumper, onboard or external power input, and a power LED. It is compatible with Raspberry Pi 2/3/4/5 and Zero models, and has been tested with I²C, serial, and other peripherals.
Its compact form factor allows it to fit within most Pi enclosures. Other features include laser-etched pin labels for easy identification, an open-source hardware design, and development by Bitmerse (Ahmedabad, India).
The product is completely hardware-based, so no special drivers are required. It works with Raspberry Pi OS, Raspbian, and other Linux distributions, as well as other environments and Raspberry Pi-compatible development boards like the XPI-3576 industrial SBC, the Ebyte ECB31-PB, the XpressReal T3 AI SBC, and others. All GPIOs retain their functions, ensuring existing software, libraries, and frameworks such as Python GPIO, WiringPi, and I²C/SPI drivers continue to work without changes.
The bPiShift will launch soon on Crowd Supply, with pricing to be announced at campaign start. Interested users can sign up for updates, and worldwide shipping will be handled by Crowd Supply once the campaign is funded. More information about the products can be found on the company’s GitBook page.
