MoPi is a piddling anon circuit board that plugs on overstep of the Raspberry Pi board in addition to allows you lot to plug inwards all sorts of ability supplies such every bit a measure rechargeable AA battery pack, solar panels or a chunky ability brick supply. You tin give notice fifty-fifty plug ii dissimilar ability supplies at once. You tin give notice hot swap ability supplies without stopping work. If you lot are inwards the motorcar you lot tin give notice plug inwards your Raspberry Pi via the measure cigarette lighter plug.
MoPi consists of a 5-volt switching agency regulator in addition to microcontroller ADC (Analogue to Digital Converter) which shuts downwards the Raspberry Pi cleanly when batteries discharge. MoPi besides gives a laid upwards of warning bird states (power off, battery empty, battery bird critical, battery bird low, battery bird good) earlier it shuts downwards to give you lot a adventure to swap inwards some other ability supply. The MoPi microcontroller supplies these states via iii Raspberry Pi GPIO pins (and besides sets on-board indicator LEDs accordingly).
When working alongside the Raspberry Pi, it's ever handy to know when the battery is full, when it is starting to teach depression in addition to when it is critical. The fact that the MoPi is able to give you lot those signals both when logged inwards to the Pi in addition to visually from the battery pack itself it's really a useful characteristic to cause got on board!
MoPi solves the job of mobile ability for the Pi past times beingness able to regulate to provide the constant five volts at upwards to around 1 amp that the Raspberry Pi requires, every bit good every bit taking help of all the functions related to voltage bird monitoring, bird signalling (via the LEDs in addition to the GPIO interface), in addition to on/off switching of the +5V provide to the Pi.
