Overview
Overview of Ringo’s Parts:
Power Switch:
This turns Ringo on and off. Click it forward to turn Ringo ON,
click it rearward to turn Ringo OFF.
Battery:
Ringo contains a 240 mAh Lithium Polymer battery, sometimes called a
“LiPo” battery. LiPo batteries are awesome for a few reasons, but they do have a
down side. If the battery is discharged too far, it becomes permanently damaged.
Lucky for you, Ringo has a part onboard called a “voltage monitor”. It’s a little
part that looks at battery voltage all the time, and if that voltage drops below 3.0
volts, it will immediate turn Ringo off, and will allow him to turn back on once the
voltage is increased by charging the battery. All this to say, you don’t have to worry
about discharging Ringo too far. He will take care of himself if he is left on or run
too long without a charge. If you notice Ringo is tending to reset on his own, it is
likely because the battery voltage is getting low. Turn him off and plug him into a
charging source for a while and he’ll be happy again.
Charging Ringo:
Ringo has a self contained battery charging circuit. Whenever
he is plugged into a power source via either the Charging USB Port or the
Programming Port, he will automatically charge his battery. This happens whether
the Power Switch is turned on or off. It is okay to run Ringo while charging. The
charger will automatically turn off when Ringo’s battery is full (about
4.2 volts), so you cannot over charge him. Just plug him in and let
him handle it. Whenever Ringo is charging, the RED Charging
Indicator will be lit.
