Preeminent news from Logic IO!

In this newsletter, we have the rare honor of introducing a brand new product series based on an entirely new hardware platform coined the LX hardware architecture!
The primary motivation for a new hardware architecture is to push the boundaries of the functionality, power, and flexibility of RTCU devices at a given price level. The RTCU LX5 series is the first member of the LX family - but certainly not the last!

Before introducing the RTCU LX5 series, we are excited to announce a new RTCU NX-200 variant called the RTCU NX-200 DR. This device supports Automotive Dead Reckoning (ADR), offering unprecedented GNSS performance in difficult environments, such as in an urban jungle with high-rise buildings, tunnels, etc.
There is full support for the ADR functionality in the latest firmware and RTCU IDE, including the configuration of wheel-tick input, etc.
Please refer to the product page for the RTCU NX-200 DR.



The RTCU LX5 pro and the RTCU LX5 eco  are the very first members in the new cost-effective LX generation of RTCU devices that combines the powerful NX32L architecture from devices such as the RTCU NX-200 with the hardware simplicity and cost-level of devices such as the RTCU CX1

With the LX hardware architecture, the RTCU LX5 series offers an unprecedented balance between price and performance and is at the same time positioned for a broad range of automotive and industrial Internet of Things applications.

Technical Highlights for the RTCU LX5 pro:


  •  Based on the RTCU M2M Platform.
  •  NX32L (NX32 for Linux) execution architecture.
    •  RTCU IDE development tool.
    •  Operates under a full and highly optimized Linux variant.
