Bus Pirate v3 is a universal bus interface that talks to electronics from a PC serial terminal. Get to know a chip without writing code. Eliminates a ton of early prototyping effort with new or unknown chips. A laser cut acrylic case for Bus Pirate v3.6 is also available.This board provides 1-Wire, I2C, SPI, JTAG, asynchronous serial (UART), MIDI, PC keyboard, HD44780 LCDs, and generic 2- and 3-wire libraries for custom protocols.FeaturesUSB interface, USB powered5-volt tolerant pins-0-6volt measurement probe1Hz-40MHz frequency measurement1kHz-4MHz pulse-width modulator, frequency generatorOn-board multi-voltage pull-up resistorsOn-board 3.3volt and 5volt power supply with software resetMacros for common operationsBus traffic sniffers (SPI, I2C)Transparent USB to serial bridge mode10Hz-1MHz low-speed logic analyzerCustom support in AVRDUDE , Flashrom , OpenOCDAVR STK500 v2 programmer cloneScriptable from Perl, Python, etc.A bootloader for easy USB firmware updatesUses DP6037 standard PCB layoutOpen source (CC 0/Public Domain)
