The Relio R9 delivers RISC computing power with unmatched I/O features and uses the latest embedded software environment.

The Relio R9 is an application-ready platform for your next product design. The system is based on the 200MIPS Atmel AT91SAM9263 microcontroller boasting a 32-bit ARM instruction set for maximum performance. With up to 256MB RAM and 256MB Flash memory, the unmatched I/O features of the Relio R9 extend the possible uses beyond traditional ARM applications. The Relio R9 is the perfect platform for embedded applications requiring small size, wide operating temperature range, and flexible I/O connectivity.

Standard I/O includes Ethernet, serial, USB, CAN bus, digital and analog interface. System designers can directly drive TFT/STN LCDs from the internal video controller and the onboard resistive touchscreen controller, making it perfect for human-machine interface applications.

To provide the fastest time to market, the Windows CE 6.0 BSP binary and low-level drivers for system I/O are included. Additionally, the Relio R9 software package is equipped with the Sealevel Talos I/O framework, which offers a high-level, object-oriented .NET Compact Framework (CF) device interface. This interface provides an I/O point abstraction layer with built-in support for the specific needs of analog and digital I/O such as gain control and debouncing.

For embedded Linux systems, Sealevel provides fully configurable components – cross-compilation toolchain, bootloader, kernel and root filesystem – using a customized BuildRoot with Sealevel patches, additional features, and source code samples.

The Relio R9 is housed in a rugged, small enclosure suitable for mounting almost anywhere and is rated for a full -40°C to 85°C operating temperature range. The Relio R9 is powered from your 7-30VDC source, or select from a variety of Sealevel power supply options.

A QuickStart development kit is available, which includes the most common accessories. For applications with specialized hardware requirements, developers can use the Relio R9 as a platform for application development while Sealevel designs a customized target system specific to the user’s application requirements.

1 review for Relio R9 ARM9 Embedded RISC Computer

  1. LinuxGuy

    Versatile Embedded Device
    This is an excellent product. Plenty of I/O for any application. Even includes USB for anything else you need. (Wireless, etc.) Low power and accepts a wide voltage range. Clean board design. I have used 2 of these devices in a 24/7 environment for 4+ months with no problems. Very solid device.
