Pentium instruction set architecture
(ISA)-compatible processor
• 16 KByte L1 cache
• 512 KBytes of on-die embedded SRAM
• Simple to program: Single thread, single core, constant speed
• ACPI compatible CPU sleep states supported
• An integrated Real Time Clock (RTC), with an optional 3V "coin cell"
battery for operation between turn on cycles.
11 ICSP
6-pin in-circuit serial programming (ICSP) header, located appropriately
to plug into existing shields. These pins support SPI communication
using the SPI library.
12 256 MB DDR3 RAM 256 MByte DRAM, enabled by the firmware by default.
13 Arduino Interface
Complies with Arduino Uno Revision 3 pinout. See Section 2.4 for
details.
14 JTAG Debug Port 10-pin standard JTAG header for debugging
15 GPIO Expander GPIO pulse width modulation provided by a single I
2
C I/O expander
16 Micro SD slot (Optional) Supports micro SD card up to 32 GBytes
17 5V Power
The board is powered via an AC-to-DC adapter, connected by plugging a
2.1 mm center-positive plug into the board's power jack. The
recommended output rating of the power adapter is 5V at up to 3A.
18 Voltage Regulator
Generates 3.3 volt supply.
Maximum current draw to the shield is 800 mA.
19 Eth PHY Ethernet Physical layer transceiver
On back of board, see Figure 1.
Full PCI Express* mini-card slot, with PCIe* 2.0 compliant features:
• Works with half mini-PCIe* cards with optional converter plate
• Provides USB 2.0 Host Port at mini-PCIe* connector
