Hexiwear Workstation
POWER SUPPLY
The Hexiwear Workstation board features an effi cient and clean power supply, which
provides steady voltage levels and current, necessary for powering each part of
the board. To power on the board, it is necessary to turn the ON/OFF switch to ON
position, located at the top left corner of the board. The power presence is indicated
by the green LED indicator, located next to the switch. Once powered, the Hexiwear
Workstation board will supply the connected (docked) Hexiwear platform with the
power, charging its internal battery. Please note that the power consumption will be
greater than specifi ed, while the battery of the docked Hexiwear is charging.
