I tried to use the Yùn with the DS1302 but It seems doesn't work.
Do you have ever tried?

DS1302 is RTC.

Yun = Atmel/ATmega32u4 + Atheros/AR9331.

AR9331 does not support RTC, but ATmega32u4 does.

Leonardo=Atmel/ATmega32u4

Post same question at other forum? or get an Arduino Leonardo board to test.
