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.

Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
