tx-reverse-160pxTX25, low-cost, industrial ARM module

tx25Production-quality system-on-module (SOM) based on 400MHz Freescale i.MX25

TRITON TX25 is an ultra-low-cost SBC module, featuring industrial temperature specification, implemented on a board with form-factor smaller than a credit card (68mm x 26mm), and ready to be incorporated into your low or medium volume product manufacture or prototype. TRITON-TX25 modules are based on a 400MHz Freescale i.MX257 (optionally i.MX258) ARM9 processor with 64MB SDRAM and 128MB Flash, and come complete with a StarterKit development system, and a production quality implementation of Windows CE 6.0 or Linux 2.6.

TRITON TX25 includes a comprehensive set of peripherals and interfaces. These include USB 2.0 Host and on-the-go, Ethernet, SD Card, UARTs, LCD controller, keypad controller, I2C, I2S, AC’97, SPI, CAN and GPIO

calendarGuaranteed lifetime is a key reason to choose us – some TRITON products have already been shipping for over 10 years. The TRITON-TX module family is guaranteed to be available, in small or large quantities for at least 10 years. This is a minimum, with expected lifetimes of 15 years where possible. Direct Insight brought the first system-on-module to market in 1999, and has a unique track-record in maintaining partnership with our customers for the long-term, supporting you throughout the product life-cycle.
euBecause the TRITON-TX modules are manufactured in a high-quality small-batch production facility within the EU, there are never problems with manufacturing standards or with supply. If you order 100 modules and we don’t have them in stock, we will make them. Often, cheap modules are produced in large batches by volume-oriented contract manufacturers in the Far East, and once they are gone, they are gone.
tickOur BSPs for both Linux and Windows CE are complete, and are designed so that you can use them without further development or modification. One of the key advantages of the system-on-module approach is rapid time-to-market, and requires a reliable, production-ready BSP, and a ready-to-roll compatible tools setup. For Linux, we supply a pre-configured VM SDK, and for Windows CE, everything is ready to use with Microsoft’s downloadable toolkit.
compatibleFurther to our 10-year longevity guarantee, additional security is provided by the pin-compatible nature of the TRITON-TX range, which means that suitable baseboard designs can take all the modules from this family, including those based on i.MX25, i.MX27, i.MX28, TI AM3354, i.MX51, i.MX53 and i.MX6, and allows older modules to be replaced by the latest designs, with new features, better price-performance, and renewed longevity.
directinsight-logo-100pxStriving for the best technical support provision to our customers is what makes Direct Insight stand out. Using a system-on-module is all about achieving a quicker, smoother route to project completion. We have supported our customers in many hundreds of system-on-module projects over the last 15 years, and are uniquely placed to assist you.

The StarterKit-5 provides a complete development environment based on TRITON-TX25, running Linux 2.6 or Windows Embedded CE 6.0 out-of-the-box. The whole system is USB-powered, so requires no external PSU (except when used with optional touch-screen).


The development system consists of a baseboard which provides connectors for all the module interfaces, and includes additional peripherals such as an SGTL5000 audio codec, TSC2007 touchscreen controller and video DAC. A range of resistive and capacitive touch screens are available for optional supply with StarterKit-5.

For production purposes, you will require a custom baseboard, and we are happy to offer baseboard design and manufacture as a service.

Simply order the StarterKit-5 for TRITON-TX25 development system via our online shop, and it should be with you in a couple of days. We look forward to providing you with knowledgeable, professional support to create your product.
