BusPirate v3 is a universal bus interface that communicates with electronic devices of PC serial terminals, eliminating the need for extensive early prototype design work when using new or unknown chips.
If you are just using Bus Pirate, we still recommend v3- it is cheaper, more reliable, and has all the same main features. Compare Bus Pirate v4 vs v3. Protocol 1-Wire, I2C, SPI, JTAG, UART, MIDI, PC keyboard, HD44780 LCD, and universal 2-wire and 3-wire libraries for custom protocols.
