Bus Pirate v3 (assembled)

Introduction

The BusPirate v3 is a universal bus interface that talks to electronics from a PC serial terminal, eliminating a ton of early prototyping effort when working with new or unknown chips.

Protocols: 1-Wire, I2C, SPI, JTAG, asynchronous serial (UART), MIDI, PC keyboard, HD44780 LCDs, and generic 2- and 3-wire libraries for custom protocols.

Features

  • USB interface, USB powered

  • 0-5.5volt tolerant pins

  • 0-6volt measurement probe

  • 1Hz-40MHz frequency measurement

  • 1kHz – 4MHz pulse-width modulator, frequency generator

  • On-board multi-voltage pull-up resistors

  • On-board 3.3volt and 5volt power supplies with software reset

  • Macros for common operations

  • Bus traffic sniffers (SPI, I2C)

  • A bootloader for easy USB firmware updates

  • Transparent USB->serial bridge mode

  • 10Hz-1MHz low-speed logic analyzer

  • Custom support in AVRDUDE, Flashrom

  • AVR STK500 v2 programmer clone

  • Scriptable from Perl, Python, etc.

  • Translations (currently Spanish and Italian)
