This is a thermal printer like you would find on a cash register or adding machine. It will print simple strings passed to it via TTL serial, bitmap images (poorly) and it even generates several different formats of barcodes!

This Car Diagnostics Kit allows you to interface with your car&rsquos OBD-II bus. It provides you a serial interface using the ELM327 command set and supports all major OBD-II standards such as CAN and JBUS. The board also provides a footprint which mates directly to our FTDI Basic or a Bluetooth Mate.

We have no idea what USB device you are hooking up to, but if you want to access the microUSB port on something, you might want this.
