Title: AVRISP2 work at 3.3V?
Post by: Admin on February 26, 2010, 04:20:35 AM
Can someone tell me if the AVRISP2 programmer works at 3.3V? I can't seem to find voltage information anywhere, not even in the datasheets . . . (FYI my mcu will be powered at 3.3V)

Yes. Even the AVRISP (not version 2) works at 3.3V.
