Technical Articles Power Consumption

If you have tried to power the AYUCR Camera Controller with a 12V lighter battery you may have found the circuit drains the batter relatively quickly. The typical 12V lighter battery has a capacity of 30-33mAh.  A typical 9V battery has almost 20 times more capacity.  It is fairly easy to run these small batteries down if you're not careful.

The original 8pin and 18pin Camera Controller kits used some components that drew more power than necessary.  In addition the timer firmware itself didn't do all it could to conserve power.  These problems have been corrected for kits based on V1.53 of the firmware and later.
