The heart of the GESBC-3130S is the LPC-3130 which is the one in a series of ARM926EJ-S-
based processors. The NXP LPC3130 combines an 180 MHz ARM926EJ-S CPU core, high-speed
USB 2.0 On-The-Go (OTG), up to 192 KB SRAM, NAND flash controller, flexible external bus
interface, four channel 10-bit ADC, and a myriad of serial and parallel interfaces in a single chip
targeted at consumer, industrial, medical, and communication markets.
The list below summarizes the features of the GESBC-3130S.
•180MHz Processor Core – ARM926EJ-S with MMU
•32 MB SDRAM
•128MB NAND FLASH
•4 channel 10-bit Analog-to-Digital Converter (ADC
•RS-232 Universal Asynchronous Receiver / Transmitters (UART)
•High speed USB OTG Port
•Real-Time Clock with battery backup
•SD/MMC Socket
•GPIO Ports
•1 I2C Ports
•1 SPI Port

Chapter 2 – Getting Started
This chapter describes the GESBC-3130S working environment and familiarizes the user with its
components and functionality. This chapter contains the following sections:
•Assembly and Connections
oDescribes how to assemble and connect components to the GESBC-3130S Single
Board Computer
•Operation
oDescribes how to operate the GESBC-3130S Single Board Computer
Assembly and Connections
In order to use the GESBC-3130S the user must first assemble and connect the peripherals to the
GESBC-3130S, as described in the following procedure.
1. Place the GESBC-3130S on a static free surface.
2. Make sure all of the jumpers are in the factory default position. The unit is shipped in a
factory default configuration. If the user is uncertain that the GESBC-3130S has the
jumpers in the factory default configuration, please see the next section regarding board
configuration.
3. Connect 5V regulated power supply to CON11 on the board.
4. Connect null modem serial cable between GESBC-3130S debug port and PC/terminal
serial port.
5. Launch a terminal emulator, such as HyperTerminal, or Minicom, on the PC configured to
connect to the serial port of the GESBC-3130S. Configure the serial port with the
following parameters: 115200 bits per second, 8 data bits, no parity, 1 stop bit, no flow
control.
Operation
A few seconds after applying power to the GESBC-3130S, debug information will be displayed on
the terminal program. The following figures show what this should look like.
