ARM JTAG Adapter

There are primarily three different connectors used for programming ARM processors via JTAG:

• 20-way 2.54mm: Traditional JTAG connector that is found on most programmers and debuggers.
• 20-way 1.27mm: Pin for pin compatible with the 20-way 2.54mm, but simply saves space on the target board.
• 10-way 1.27mm: A minimised JTAG connector that is widely used for ARM Cortex devices.

This adapter board can be used to connect an ARM Cortex board using the 10-way 1.27mm connector or a board using a 20-way 1.27mm connector to a standard debugger / programmer.
