Bus Blaster v2 JTAG debugger is back in stock at Seeed Studio.The cool thing about the Bus Blaster is that it uses a programmable logic chip as a buffer. It can imitate different types of programming hardware with a simple USB update.
This batch is a new revision (v2.5). It includes a button and LED connected to the CPLD breakout pins. The local power selection header (JP4) was also moved to the edge of the PCB.
You can get a Bus Blaster v2 for $34.95.
