bPiShift is a compact, plug-and-play logic-level shifter that connects directly to the Raspberry Pi’s 40-pin GPIO header. It bridges the 3.3 V GPIO logic of your Pi with 5 V sensors, microcontrollers, or serial devices - safely and cleanly, without messy jumper wires or breadboard clutter.
Designed to simplify prototyping and protect your hardware, bPiShift lets you expand your Raspberry Pi’s possibilities while maintaining full compatibility and convenience.
Unlike typical level-shifting modules that require tangled wiring, bPiShift plugs directly into the Pi header. Its precision-aligned connector ensures a secure fit without blocking ports or interfaces. The result? A neat, professional-looking setup that minimizes wiring errors and signal noise-ideal for both prototyping and deployment.
bPiShift uses proven MOSFET-based bidirectional circuits to ensure reliable voltage translation in both directions. Whether you’re working with I²C sensors, serial peripherals, or custom digital logic, it maintains proper logic levels and prevents accidental over-voltage damage to your Pi’s GPIOs.
Designed specifically for Pi 2/3/4/5 and Zero series boards, bPiShift is mechanically and electrically compatible with the entire Raspberry Pi lineup. It’s small enough to fit inside most standard Pi enclosures and keeps access to key peripherals open. From classroom projects to embedded systems, bPiShift brings a new level of safety and simplicity to every build.

bPiShift is an open-hardware project. The schematics and production gerber files are publicly available on our GitHub repo.
bPiShift will be produced by our contract manufacturing partner in India. The final PCB assembly, testing, and quality inspection will take place at Bitmerse LLP in Ahmedabad, Gujarat, India.
Our production test fixture automates GPIO validation and voltage-shift accuracy checks before packaging.
Once production and QA are complete, units will be packaged and shipped to Crowd Supply for global fulfillment through their logistics partner, Mouser Electronics. Bitmerse will handle all pre-shipment inspections, labeling, and kitting to ensure a smooth delivery experience. For details on ordering, payment, and shipping, refer to Crowd Supply’s fulfillment guide.
As with any hardware product, there are risks around component availability, manufacturing delays, and logistics. Having successfully funded, produced, and shipped (WiSer), however, we already have trusted supply-chain and production partners. Should any unexpected issues arise, we will communicate transparently through project updates on Crowd Supply and detail our mitigation steps. Our goal is to ensure timely fulfillment and reliable performance for every backer.
