1 leanXcam
1.1 Introduction
leanXcam is an intelligent colour camera with a rich set of features that provides an impressive
performance, in spite of its low production cost. The smart combination of a well-established sensor
chip, a fast digital signal processor, a tailored Linux-based operation system and the image processing
framework from SCS-Vision makes the leanXcam an incomparable achievement in the field of Vision.
Communication is ensured by Ethernet connection and digital I/Os.
1.2 Purpose of this document
This document gives an overview of the leanXcam HW and provides information about the used
devices, interfaces and some examples. This document should be used by readers who are interested
in the physical blocks contained in the leanXcam or by readers who want to use more debug features
like RS232 and JTAG, when designing with the leanXcam.

2.2 On-Board Devices
The leanXcam board offers the following devices:
-500 MHz Digital Signal Processor Blackfin ADSP-BF537
-CMOS Sensor Micron MT9V032C12STC (color) or MT9V032C12STM (monochrome), Wide-
VGA 752H x 480V, 10Bit
-64 MByte RAM Memory
-4 MByte Flash for Boot program
-4 MB Flash Memory for Algorithm Software
-microSD Card holder for optional Flash Memory expansion
-Voltage Regulator (LDO) for clean and stable 3.3V Supply Voltage
-Lens holder for standard M12x0.5 mount Lenses
2.3 Interfaces
The leanXcam Board supports the following interfaces:
-Fast-Ethernet 100Mb (10/100Mb) (RJ-45 Connector)
-RS232C Interface for first-time configuration during manufacturing (on-board header)
-I2C Interface to connect additional serial devices (on-board header)
-JTAG for Debugging DSP (on-board 14-pin 2-row header)
-5V Power Input (6.5mm round connector Lumberg 1613 14)
-2 optical isolated inputs and 2 optical isolated outputs (isolation can be jumpered, 1 input can
be used as external exposure, 1 output can be used for external flash triggering) with a 6-pin
Phoenix direct-PCB connector. Also see Figure 2 and Figure 3 for details
-Power-ON LED (on-board)
-Link speed und Link activity LED (in RJ45 connector, external view)
-Bi-color status LED (external view)
