Bus Pirate - BPv3.6

This is a great product. I have been using it to test many different types of sensors like temperature, pressure, gas, humidity, and many other ICs that use industry standard protocols like I2C, SPI, UART (these are the most used). It's very easy to use, it works on Windows and Linux, using any serial application like Putty (Windows) and minicom (Linux). The user interface is via command line, but it's very easy to use, with its set of hierarchical menus.If you have never used a Bus Pirate, please pay attention to one detail - before testing any sensor you need to turn on the power in the pins, issuing the command 'W' inside each protocol menu.It's important to note that the USB port is mini and not micro.
