The OnRISC Baltos iR 2110 is a fanless and DIN-Rail mounting suitable industrial embedded PC with very compact dimensions. It is based on an ARM Cortex-A8 with NEON SIMD Coprocessor, with up to 1GHz CPU clock speed. Low power consumption (3W typical), an extended temperature range (−20°C to 65°C), a wide power supply (12 — 50V DC) and an impressive MTBF (13 Years at 45°C) are qualities that make it an ideal system for industrial automation. iR 2110 is fully ESD and surge protected, complying with IEC 61000-4-2 (8KV air and 4KV contact).

IoT-Cloud Support

Thanks to it's rich connectivity Baltos devices can be used as IoT Gateways connecting sensors/actuators and arbitrary cloud providers like Amazon's AWS IoT, Microsoft's Azure IoT Hub and others using MQTT protocol directly or via the cloud providers own APIs.
Besides Baltos series can also serve as a controller. Both roles can be easily programmed using either traditional programming languages or Node-RED*, a visual flow-based programming for the Internet of Things.

Easy-to-use starter kits

Baltos embedded systems run several Linux flavored distributions on an ARM core as an operating system. In addition, two pre-packaged bootable SD cards are provided: The Debian GNU/Linux and an upstream OpenWrt image; the latter includes an install-option to the internal flash memory. A VPN router firmware specialized in easy-to-use VPN networking is also available (VPNRouter).

Booting options and BSPs

Baltos iR 2110 can be booted from either NAND flash or microSD card. The NAND flash is a robust boot medium capable of withstanding power cuts and vibrations. microSD cards have the advantage of providing arbitrarily large storage amounts. Buildroot, Yocto and OpenWrt BSPs provide a small footprint and would fit well into the NAND storage, whereas Debian is best used on the microSD card.

Rich connectivity

WLAN802.11b/g/n is available as a common option; furthermore, two locations for SMA-antenna sockets are provided. The balanced variety of interfaces such as LAN, USB, RS232/422/485 serial ports and microSDHC enable Baltos iR 2110 to act like a powerful gateway between networks, various industrial devices and field buses.

Secure Remote Access

For the Baltos series there is a software option that uses the viaVPN Cloud system (, which can be remotely accessed and monitored over the Internet. viaVPN provides secure and strongly encrypted access, without the need for any reconfiguration of existing firewalls. In case a customer's firmware/application is accessible via Ethernet or Wifi — as for example via a web interface or Telnet/SSH connection — viaVPN extends the access over internet by a protected VPN tunnel.

  Software Specifications


Latest stable release available as ready-to-run SD card image or can be built/customized via ELBE project (Github)
BSP with Kernel and bootloader patches and basic configuration (Github)
layer-baltos with Kernel and bootloder patches suitable for new projects or integration into already available projects (Github)
Buildroot and Yocto are suitable for installation to NAND Flash


Based on branch DD 'Designated Driver', comes ready-to-use on a microSD card. Installation into NAND Flash memory is supported.
To self-create this software the setup procedure is on GitHub.

Remote Access (option)

The daemon to access the viaVPN system provides secure Remote Access over Internet. It supports a Debian-based Installation, and Buildroot as well.

Connect via Internet
viaVPN provides easy access to remotely installed systems. Software installation is quickly done with convenient tools to get access from everywhere.
All communication uses a VPN-tunnel encrypted by SSL/TLS and AES-256.
Firewall friendly, ready for 3G/4G use
viaVPN Cloud Server access uses common web ports. Reconfiguration of firewalls is not required. This enables the use with mobile networks.
