original power adapter cable is not wise as the voltage reaching the eSynC may be too low due to
cable losses.
When the mobile device is charging, up to 1.3 amperes of current is offered to the device. The
power consumption of the LAVA board is negligible. The power supply for an eSynC-1U-OEM
should have a capacity of at least 1.8 amperes to allow for power required by an attached USB
accessory. The power supply for an eSynC-BM-OEM should have a capacity of at least 1.3
amperes.
The input voltage to the board should be at least 5 volts for proper device operation. Any 5-volt
regulated DC power supply can be used with these boards, including USB Power banks. The
preferred voltage at the board input is 5.1 to 5.25 volts. The board input voltage
must not
exceed
5.25 volts.
Due to power loss across the connecting cables, the designer must ensure that the voltage is not
too low at any point in the system. Power loss is an issue that applies to all USB cables in the
system.
The power supply used to run the system is responsible for handling over current conditions.
The power connectors have no protection against overvoltage or reversed connections.
Application of the wrong voltage can result in
immediate
damage to the board and possibly
other components in the system.
Ethernet-related features described in this document do not apply to these boards.
Application of the wrong input voltage violates LAVA’s Manufacturer Warranty.
