The pinout of the JTAG connector on the AVRcard core module follows the convention of the JTAG Programmer/ICE of E-Lab Computers.

However, this pinout differs from the one used on the Atmel JTAG ICE mkII and other compatible products. In order to use these products in conjunction with the AVRcard, a conversion adapter is needed. Below you find the information required to build such an adapter..
