The Micromint picoJTAG is a low-cost debugger for ARM Cortex M3 microcontrollers. It combines JTAG debugging with a RS-232 Virtual COM port allowing software developers to connect a debugger and serial port to a computer with a single USB cable. The picoJTAG can also provide power to targets that are capable of accepting power on the 20-pin JTAG connector. Drivers are provided for IAR, Keil and GNU toolchains supporting ARM Cortex M targets. Third party FTDI debugger drivers can be used to support other targets.
