Raspberry Pi Zero PiTrezor Hardware Wallet PCB

🔐 Raspberry Pi Zero – PiTrezor Hardware Bitcoin Wallet PCB

📌 Overview

This project is a DIY open-source hardware cryptocurrency wallet based on the Raspberry Pi Zero, inspired by the original PiTrezor by Dmitry Nedospasov. It replicates the core functionality of a commercial Trezor device, enabling fully offline storage and signing of cryptocurrency transactions through a simple physical interface.

With a custom-designed PCB, OLED screen, and two tactile buttons, this wallet offers a compact and affordable solution for secure crypto storage using the Raspberry Pi platform and Trezor-compatible firmware.

🎯 Key Features

• 🔐 Cold Storage: Private keys never leave the Raspberry Pi.

• 🖥️ OLED Display: View transaction info before approving.

• 🔘 2-Button Interface: Confirm or deny transactions manually.

• 🔌 Micro USB Powered: Fully portable and USB-powered.

• 🧩 Trezor Web Wallet Compatible: Use wallet.trezor.io to manage your crypto.

• 🛠️ Custom EasyEDA PCB: Simplifies hardware connection for repeatable builds.

🔧 Hardware Components

⚙️ Firmware & Software

• Firmware: Trezor Firmware GitHub

• PiTrezor Image & Scripts: PiTrezor Guide

• Web Wallet: https://wallet.trezor.io

🧪 How to Flash & Use

1. Download the PiTrezor Linux image from the official PiTrezor website.

2. Flash the image to a MicroSD card using Balena Etcher or Raspberry Pi Imager.

3. Assemble hardware using the schematic (RPI.pdf) – connect the OLED and buttons to GPIO.

4. Boot the Raspberry Pi Zero with the SD card inserted.

5. Visit https://wallet.trezor.io from a computer and connect the device via USB.

6. Use the two-button interface to verify and sign transactions directly on the device.

⚠️ Security Warnings
