Page 17: Connectors Description
The inner and outer diameters of the mating plug are 2.0 mm and 5.5 mm respectively. Fan/12 V Internal Power Connector (J1302) The Mars EB1 base board can alternatively be powered through the internal power input connector. The 12 V DC power source connected to J1302 must be filtered by external power circuitry. -
Page 18: I/O Voltage Selection (J1200)
The power and data signals on this connector are ESD-protected. 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. -
Page 19: Gigabit Ethernet Port (J900)
The power and data signals on J401/J402 connectors are ESD-protected. 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. -
Page 20: Microsd Card Slot (J800)
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. -
Page 21: I/O Connector D (J1103)
The battery holder and battery are not mounted in the standard configuration of the Mars EB1 base board. The battery on the Mars EB1 base board is used for buffering the real-time clock on the connected Mars FPGA/SoC module. If required, a 3 V lithium battery (CR1220) can be used. -
