Power and Power-On Sequence
Power Consumption
To power-up a module, power supply with minimum current capability of 1A is recommended.
Power Supply
The FPGA module can be power-supplied through Micro USB2 connector J9 with supply voltage 'USB-VBUS' or alternative through pin header J2 with supply voltage 'VIN'.
The TEI0010 module needs one single power supply of 5.0V nominal.
There are following dependencies how the initial voltage of the extern power supply is distributed to the on-board DCDC converters:
