Introduction

This document shows the pinouts for the EB2410ITX. Several special function pins exist which may be changed to simple GPIO if the special function is not required. Some pins have more than one special function which should be taken into account.

The EB2410ITX has a large number of peripherals, not all of these peripherals are fully realised with physical connectors. For example there are up to five serial ports available (three from the S3C2410 and two from the superIO controller) and only enough physical space for a single external 9way D type and a single internal Box header. The remaining serial ports are available as LVTTL signals from a pin header array. This is typical of the design of the EB2410ITX in that we attempt to make all signals available in a useful form.

Since the EB2410ITX was released SD/MMC has become more popular than the Smartmedia originally provided for. The SD/MMC port is available via the 50 way 2mm expansion header and can be brought to an external connector if desired. These pins were originally designated for the simple keyboard matrix which cannot be fully used if SD is required.

The PC104 connector allows for even more expansion possibilities. There is provision for alternate power supply voltages, links LK1 and LK22 select between 3.3V and the more normal 5V.

LCD Module

The LCD module interface is distinct from the main LCD video display, it provides an eight bit parallel interface to LCD modules, the chip select and address decode is performed by the system CPLD and allows for direct connection of two HD44780 type modules with a simple ribbon cable (the second module connection must be made to use the second enable line).

IDE

A pair of standard parallel ATA (IDE) channels are provided. They are presented as on 40 way standard box header and a second 44 way laptop style connector. The two channels are buffered and isolated form the rest of the systems busses but do share a single data buffer, this may cause issues with some ATA devices (notably cheap CF cards) which do not properly qualify their data bus usage with their respective separate read and write strobes.
