TX Mainboard 7

1 Introduction

The Ka-Ro TX Mainboard 7 is an advanced development system, especially designed for building applications based on Ka-Ro’s family of TX Computer on Modules.

In addition to the comprehensive array of connectivity options which Ka-Ro has offered in the past in its development systems, the new TX Mainboard

7 now also comes with CAN, RS485 and SATA. Apart from the JTAG connector, one of the main advantages for developments is a grid of test points which can also be used for standard 0.1" pin headers.

The signals of the TX6 PCIe interface are routed as differential pairs, thus allowing connection of peripherals for testing.

The TX Mainboard 7 serves as a perfect match for Glyn’s

TFT Family Concept display series from 3.5" up to 7". It can be screwed onto the mounting lugs of the 5.7" display, thus forming a panel display unit. Further to this, a standard DF13 Hirose connector provides an LVDS interface for connecting one or two larger, higher resolution displays, e.g. full HD panels.

2.5 24 Bit LVDS remark

There is an issue on TX Mainboard version 7a. LCD[0] (LSB Blue) is missing on a 24-bit LVDS display if a standard RGB TX module is used and the 2nd channel of LVDS TX modules cannot be used because a trace has been disconnected. Refer to the latest schematics for details.
