Turtelizer 2 is an universal JTAG interface communicating with host station via USB. In my hardware implementation it has 10 pin JTAG connector. The other pins are used by RS232. It works perfectly with OpenOCD software. It’s good and cheap solution for ARM7, ARM9, Cortex, etc.  microcontroller programming.

This device was made to track vechicles and to send information about their position. The position data is fetched from GPS module, and gathered data is sent via onboard GPRS modem to central server. It can be connected to PC by usb in order to manipulate its configuration parameters.

Strength in simplicity. This AVR programmer, made of  few simple electronic parts, gives you a powerful and fast programming interface. It is 100% compatible with USBasp project.
