Quote from: LubOlimex on January 20, 2020, 12:12:51 pmThe current from the USB is not usually sufficient to power the board. In order to charge the battery the supply should be powerful enough to power the board + extra current for charging. This note in the document should not be taken lightly:IMPORTANT! The A64-OLinuXino board is fully powered by applying 5V of voltage over the power jack connector named "PWR1". The board can also be powered by a 3.7V Li-Po battery attached to the "LIPO_BAT1" connector (there is a step-up convertor to 5V, so the USB ports would still work, albeit with lower current output available). For people that want to embed the board in their own designs and find using power jack "PWR1" inconvenient, please use the pad of "FUSE2" to provide power supply (and any on-board "GND" wire or pad - good places for GND are pad #2 from "UEXT1" or pad #2 from "GPIO1" or the GND pad of the "HSIC1"). The A64-OLinuXino board CAN NOT and SHOULD NOT be powered via the micro USB connector "USB-OTG1", nor via type A female USB connector "USB1", nor via any of the "GPIO1" pads, nor via the "UEXT1" pads, nor via Ethernet connector "LAN1", nor via "HDMI1" connector, nor via "HSIC1" pads, nor via nor "IPS1" pad, etc. Some of the pins of the mentioned connectors and interfaces might have wires, pads, or pins marked as "+3.3V" or "+5V" in the schematics or in the board design files but these are outputs only and NOT power inputs.
