RISC Computing with Unmatched I/O and Windows CE 6.0Packed with a wealth of I/O features and using the latest embedded software environment, Sealevel’s Relio R9 is an application-ready platform for embedded applications requiring small size, wide operating temperature range, and flexible I/O connectivity. The unmatched I/O features of the Relio R9 extend the possible uses beyond traditional ARM applications. For the fastest time to market, Windows CE 6.0 BSP and low-level drivers for system I/O are included.

  • Enclosed in a compact, rugged package for maximum durability
  • Up to 256MB RAM and 256MB Flash memory
  • Serial, digital and analog I/O
  • Low power requirements

For applications with specialized hardware requirements, the Relio R9 can be used for development while a customized target system is designed for your specific requirements. Sealevel offers full electrical, mechanical, and software design services to supplement your in-house capabilities.

Tech Lowdown
Overcoming the Embedded Development
Learning Curve

Embedded hardware development can have a steep learning curve. To speed time-to-market, Sealevel’s Relio R9 includes the Talos I/O framework for CE 6.0. The Talos framework provides a familiar experience for .Net developers yet requires very little embedded hardware experience. Start coding immediately without the need to learn hardware details.

Learn more about the SBC-R9 (single board computer) and the Relio R9 (RISC embedded computer), which include a board support package (BSP) with Talos I/O framework and a wealth of standard I/O features.
