Atmel-ICE-header-adapter-pcb

A simple passive adapter for the Atmel-ICE, converting its fine-pitch debug header to the classic AVR ISP, AVR JTAG and SAM 2.54 mm headers. No active parts - just a clean signal re-route in Eagle.

What's populated

• ICE-AVR 10-pin input, AVR ISP 10/6, AVR JTAG 10, SAM 10 and SAM 20 headers, a 1N4148, and power pins
• Revisions in 2014 and 2015 with gerbers for each

The signal path

The ICE header's debug lines connect directly to the corresponding pins on each output header. Choose AVR-ISP or SAM depending on the chip. A 1N4148 guards the voltage sense line.
