Page 25: Battery Charger
Battery Charger Figure 14 - Battery Charger A +3.7 V Lipo battery (not included) connected to J10 can power the CHARLIE board. The battery can be charged by the onboard charger, which receives receives +5V from the VIN connector, MCU USB Native Connector or ME310 Native USB connector. - Page 26 Figure 16 Connector without temperature sensor (top) and with temperature sensor (bottom) By default, the Charlie board is configured for batteries without NTC temperature sensor. To disable battery temperature monitoring, the 10 Kohm resistor R31 is mounted. If a battery with NTC temperature sensor is connected to the board WITHOUT removing R31 resistor, the battery charger will not function.
- Page 27 CHARLIE HW User Guide WARNING Use Li-Ion battery V = 3.7V, V = 4.2V Capacity >= 700 mAh chrg Li-Po batteries are charged at 4.2V with a current that is usually half the nominal capacity (C/2). This board has a dedicated IC that has a preset charging current of 350mAh: this means that the MINIMUM capacity of the Li-Po battery shall be 700 mAh.
