I am considering replacing the coin battery in my shield design with a super capacitor. I wonder if someone else is doing this already. Any comments/suggestions? I'm using DS1307. It has a maximal I_battery of 500nA, maximal V_batt 3.5V. I intend to use the Arduino 3.3V supply to charge it to 3.3V.…
