Figure 1.1: Power circuit overview
All on-board power supplies are enabled or disabled by the power switch (SW1) or by
an external SPST switch connected to the SWT header (J13).
Note
:
If an external switch is used, SW1 should be placed in the “OFF” position, as the
two will be placed in parallel.
The power indicator LED, the topmost LED of the circuit board indicator (LD4), is
illuminated red when all supply rails reach their nominal voltage.
Two additional indicator LEDs are illuminated when the VIO supplies associated with
the two Zmod Ports are powered. LD2 is associated with Zmod Port A and the VADJA
rail. LD3 is associated with Zmod Port B and the VADJB rail.
1.1. Power Input Source
The Eclypse Z7 should be powered via a wall wart supply with barrel jack, via the barrel
connector (J11). The supply must use a center-positive 2.1 mm internal-diameter plug
and deliver between 11.5V and 12.5V DC. It should also be able to provide at least 5 A
(60 Watts) in order to support power hungry Zynq projects and external peripherals. A
compatible power supply ships with the Eclypse Z7.

1.2. Power Specifications
Table 1.2.1 describes the characteristics of the Eclypse Z7's on-board power rails. It can
be used to estimate power consumption for a project, or determine how much current
attached peripherals can draw before being limited.
