Overview
This is the 1/3 chapter of IGEPv2 Expansion Tutorial Guide.
In this first chapter, we will learn how to connect some expansion peripherals.
Requirements
In these tutorials we are going to need the following components :
- IGEPv2, +5V DC power supply, Ethernet cable and a PC with Linux or Windows.
- Powertrip 4.3" or Seiko 7" screen if you need a touch screen.
- DB9 connector and USB serial converter to follow serial communication tutorial
- 4 pin connector for CAN Bus with another IGEPv2 and Expansion to follow CAN Bus communication tutorial
- SIM card with an antenna to follow Telit modem tutorial
- Composite video cable, composite video output peripheral (PAL or NTSC) and a screen to follow TVP5151 tutorial
Getting started
Connect IGEPv2 Expansion with IGEPv2 Board
Basic
The IGEPv2 Expansion connects to the IGEPv2 Board through J990, JA41, JA42, JC30 and J960 connectors. Some IGEPv2 Expansion may include three jumpers, you should remove it because they are designed for test and lab purposes. Just take a look on the figure below to mount it:

|
IGEPv2 Expansion integrates a VGA connector, the output VGA signal is equal to HDMI connector. Plug a monitor with VGA input.
Know more
This output is controled by ADV7125KSTZ140 Integrated Circuit.
CAN bus
Basic
Know more
This output is controled by MICROCHIP MCP2515. J703 is a 3.5 mm pitch terminal blocks 4 Positions:
| Signal Name | Pin # |
Description |
| VDD_CAN | J703:1 | Supply Voltage (+5V DC) |
| CANL | J703:2 | CAN Low-Level Voltage I/O |
| GND | J703:3 | Ground |
| CANH | J703:4 | CAN High-Level Voltage I/O |
