ODALISS OBC is designed to provide high computational performance with a flexible power consumption in data-intensive space systems such as nanosatellites, microsatellites, or specialized payloads.

The ODALISS OBC is based on a dual-core processing CPU that includes a rich ecosystem of peripherals to control the most demanding avionics subsystems and payloads.

Main Features:

  • Powerful dual-core architecture: Cortex®-M7 for high-performance processing unit, and Cortex®-M4 for mission-critical systems control.
  • BC includes a 10/100Mbps Ethernet switch to seamlessly implement standard TCP/IP backplane LAN with up to 5 nodes.
  • Safety-centric architecture including RTC, voltage monitoring and watchdog.
  • Flexible logic interface (UART, RS-485, I2C, etc.).
  • CPU
    • Dual 32-bit STM32 processor unit, ARM® Cortex®-M7 + Cortex®-M4, at 480MHz, with double-precision FPU, data and instruction cache and DSP instructions.
    • Redundant (independent and window) watchdog for each core.
    • Low-voltage monitor.
  • Memory
    • Up-to 256GB eMMC NAND flash for long-term data storage. 64 MB SDRAM provides fast access to data.
    • 256KB FRAM for critical information.
    • 128MB NOR flash.
  • Connectors
    • Two 80-pins high-speed interface backplane connectors.
    • Two 5-pin for external programming and communication.
    • Pogo-style for program and debug without mechanical stress.
  • High-speed connectivity
    • Four 10/100 Ethernet ports.
    • USB port.
    • SPI with two chip-selects.
  • Standard logic interfaces
    • Three UARTS.
    • RS-485.
    • Two I2C interfaces.
  • Inputs and outputs
    • 22 GPIOs than can be individually configured as inputs or outputs.
    • Eight open-drain inputs.
    • Eight open-drain outputs.
    • Five high-current open-drain outputs.
  • Analog inputs
    • 12 analog inputs with up-to 16-bit resolution.
    • Voltage range from 0V to +3.3V.
    • Each input signal can be conditioned to measure either voltage or current.
    • Configurable active filter per channel.
  • Integration
    • Requires only a +3.3 V power supply.
    • Operating temperature: -45 ºC to +85 ºC.
    • Size: 87mm x 87mm x 10mm.
    • Weight: 45 grams.
