1Requires FPGA support (video protocol implementation)
D-0000-307-001 5 / 39 Version 06, 22.07.2021
Ensure that the power supply is disconnected from the board before inserting or removing a Mars module,
connecting interfaces, or connecting jumpers.
Touching the capacitors of the DC-DC converters can lead to voltage peaks and permanent damage; over-
voltage on power or signal lines can also cause permanent damage to the board and to the equipped
module.

the I/O banks of the SoC/FPGA device on the Mars module. Refer to Section 5.5 for details.
4.4 Mars Module Connector (J200)
A detailed pinout of the Mars module connector can be found in the Mars Master Pinout [10] and in the
Mars EB1 Base Board User Schematics [5].

Warning!
Only Enclustra Mars FPGA/SoC modules should be inserted into the Mars EB1 base board.
Warning!
The VCC_IO pins are directly connected to the FPGA/SoC device. Apply only compliant voltages to the
VCC_IO pins; any other voltage may damage the mounted Mars FPGA/SoC module, as well as other
devices on the Mars EB1 base board.
4.5 USB 2.0 Host Connector (J400)
If the mounted Mars module features a USB controller, the module’s USB signals can be connected to J400
via a multiplexer. Details on USB connections on the board are available in Section 6.5.
The power and data signals on this connector are ESD-protected.
4.6 Micro USB 2.0 Device Connectors (J401/J402)
There are two micro USB 2.0 device connectors on the Mars EB1 base board: one on the front panel and
one on the side.
D-0000-307-001 18 / 39 Version 06, 22.07.2021
The micro USB connector on the side can be connected to the on-board FTDI device, and the micro USB on
the front panel can be either connected to the FTDI device, or to the USB signals coming from the module
connector. The configuration is done by changing the position of the DIP switches - refer to Sections 6.5
and 6.3 for details.
The base board can be powered via any of the micro USB 2.0 device connectors; further information on USB
power is available in Section 5.2.
The power and data signals on J401/J402 connectors are ESD-protected.
4.7 Gigabit Ethernet Port (J900)
The Mars EB1 base board is equipped with a 10/100/1000 Mbit Ethernet port. The capability of the Ethernet
interface depends on the connected Mars module.
The RJ45 connector J900 is connected through magnetics directly to the Mars module connector. For details
on the Ethernet interface, refer to Section 6.4.
4.8 Mini Camera Link Connectors (J600/J700)
The Mars EB1 base board is equipped with two Mini Camera Link connectors. The signals available on these
connectors are routed directly to/from the FPGA banks on the SoC/FPGA device on the Mars module.
Power over Camera Link (POCL) for the two connectors can be activated via two enable signals: PWR_EN_CAM0
and PWR_EN_CAM1. These signals can be toggled by writing the corresponding registers in the system con-
troller - refer to section 6.10 for details. By default, the power over Mini Camera Link is not active.
The signals on the connectors have no termination resistors and they are ESD-protected.
The pinout on the J600/J700 connectors corresponds to the Mini Camera Link standard maintained by AIA
(Automated Imaging Association). In order to receive and transmit video signals through the links, FPGA
support is required (video protocol implementation).
4.9 HDMI Connector (J1000)
The Mars EB1 base board is equipped with an HDMI connector. The signals available on this connector are
routed directly to/from the FPGA banks on the SoC/FPGA device on the Mars module.
The power connection for the HDMI is activated by an enable signal: PWR_EN_HDMI. This signal can be
activated by writing the corresponding register in the system controller - refer to section 6.10 for details. By
default, the power over HDMI is not active.
The signals on this connector have 50 Ωtermination resistors to VCC_IO_B and are ESD-protected.
The I2C communication on the HDMI connector is currently not supported. The I2C connectivity circuits
present in the board schematics are intended for future use.
The pinout on the J1000 connectors corresponds to the HDMI standard. In order to receive and transmit
video signals through the links, FPGA support is required (video protocol implementation).
The Enclustra Display Controller IP Core [3] can be easily integrated into any user design and facilitates the
development of FPGA video applications.
D-0000-307-001 19 / 39 Version 06, 22.07.2021
4.10 microSD Card Slot (J800)
The enclosure of J800 is connected to GND.
The microSD card signals can be connected via a multiplexer with a built-in level shifter to the Mars module
SDIO signals. This signal path can be activated by setting the SDIO_SEL signal to logic high. This signal is
controlled by the DIP switch CFG A 3 or by the system controller. Refer to Sections 6.3 and 6.10 for details
on configuration.
4.11 Anios I/O Connector A (J1104)
The Anios I/O connector can be used for user applications: it provides 24 user I/Os, a differential clock
connection, connectivity to the I2C bus, and power supply connections. The clock, data and I2C signals are
routed to the module connector - for details, refer to the Mars EB1 Base Board User Schematics [5].
Warning!
The Anios I/O pins are connected directly to the FPGA/SoC device. Use only VCC_IO voltages compliant
with the equipped FPGA/SoC device; any other voltage may damage the mounted Mars FPGA/SoC
module, as well as other devices on the Mars EB1 base board.
4.12 PMOD I/O Connectors B, C (J1102/J1105)
The dual PMOD I/O connectors (2 ×6) can be used for user applications: each connector provides 8 user
I/Os and power supply connections. The signals on PMOD B are connected directly to the module connec-
tor, while the signals on PMOD C are connected via 100 Ωseries resistors to the module connector and in
parallel to the system controller and to the on-board user buttons. For details, refer to the Mars EB1 Base
Board User Schematics [5].
The PMOD I/O connector B is Digilent Pmod™ compatible when VCC_IO_B is 3.3 V.
The PMOD I/O connector C is Digilent Pmod™ compatible when VCC_IO_A is 3.3 V.
Warning!
The PMOD I/O pins are connected directly to the FPGA/SoC device. Use only VCC_IO voltages compli-
ant with the equipped FPGA/SoC device; any other voltage may damage the mounted Mars FPGA/SoC
module, as well as other devices on the Mars EB1 base board.
Warning!
Do not insert a PMOD module to these connectors if the corresponding VCC_IO_[x] supply is not 3.3 V,
as this may damage the mounted Mars FPGA/SoC module, as well as other devices on the Mars EB1
base board.
