Additional Information

The TS-7400-V2 is a compact, low power, and cost competitive SBC. It is based on the TS-7400 and serves as a drop-in replacement that is less expensive, faster, and provides more features than the original. It is powered by the Freescale i.MX286 ARM926EJ-S core that is clocked at 454 MHz. The TS-7400-V2 includes a micro-SD socket and brings out many interfaces via a 40 pin header including CAN, ADC, GPIO, SPI, I2C, I2S, and UARTs. Consuming as little as 0.5W, and costing only $84 it’s a great balance of features, cost, and power consumption.

Hardware Description

The TS-7400-V2 is a small SBC that is designed to provide extreme performance for applications which demand high reliability, fast bootup/startup, and connectivity at low cost and low power, such as point-of-sales (PoS), vending machines, data acquisition units, data recorder modules, etc. Additional TS-7400-V2 specifications include:

  • 100% soldered-on components
  • Fanless -40 to 85 °C with CPU clocked at 454MHz
  • Board dimensions are 2.9" x 4.7"
  • Power consumption can be dynamically controlled via software and ranges from 0.5 to 1.2 W
  • Equipped to handle 4 Analog-to-Digital inputs, but has not yet been implemented. Call or email us if you have questions.

Software Description

The TS-7400-V2 ships with Linux kernel version 2.6.35 and Debian Wheezy preinstalled. Other software features include:

  • UBIFS filesystem preinstalled on Nand flash. The successor to JFFS2 which provides faster mounting, quicker access to large files, and improved write speeds. UBIFS also preserves or improves upon JFFS2's on-the-fly compression, recoverability and power fail tolerance.
  • Sleep mode requiring around 9mW of power, with the ability to wake up after an arbitrary timeout with a 1s resolution
  • Standby mode which consumes 250mW, and can wake in as little as 250ms
