![]() ![]() If you want to connect a battery to your MKRZero be sure to search one with female 2 pin JST PHR2 Type connector. This will limit the amount of charge to max 1400 mAh per charging round. The chip is programmed with 4 hours of charging time, then it goes into automatic sleep mode. A bigger cell will take more time to charge, but won't be harmed or overheated. We strongly recommend that you select a Li-Po battery of at least 700mAh capacity. Smaller cells will be damaged by this current and may overheat, develop internal gasses and explode, setting on fire the surroundings. This means that the MINIMUM capacity of the Li-Po battery should be 700 mAh. For Arduino MKR ZERO we use a specialized chip that has a preset charging current of 350mAh. Li-Po batteries are charged up to 4,2V with a current that is usually half of the nominal capacity (C/2). The SD library automatically recognizes the MKR ZERO and so any modification to the sketch is needed to use it apart from choosing the right SS pin (SDCARD_SS_PIN). ![]() Furthermore, SD card is driven by a dedicated SPI interface (SPI1) and so any of the pins of the header is busy during SD usage. The onboard SD connector allows you to play with files without adding any extra hardware to the board. ![]()
