Major news from Logic IO!

Back in May 2006, we made history by introducing the RTCU MX2 professional device. At that time, this was one of the most advanced automotive devices on the market, and it was well-received by our customers.
Over the years, several facelifts were made to meet the requirements of our customers - the latest with the RTCU MX2 turbo LTE in 2019.
The MX2 is undoubtedly our most successful device over the last 20+ years - not only in terms of volume but also as a technological milestone that impacted all devices after that.

We are therefore extremely humble when we today announce the successor to the RTCU MX2 legacy - Welcome to the RTCU LX2 pro!

The RTCU LX2 pro is a powerful successor to the RTCU MX2 turbo with significant features, capacity, power and security improvements.  The RTCU LX2 pro is based on the latest LX hardware architecture, offering an unprecedented balance between price and performance.

The RTCU LX2 pro is designed to meet the ever-increasing challenges on security, in that it offers full TLS on all major protocols. It includes a hardened protected execution environment with dual-boot and automatic fallback and recovery.

The RTCU LX2 pro  device is designed from the ground up for professional M2M / IoT applications with strong onboard I/O capabilities and multiple communication interfaces such as LTE Cat.4, BLE, CAN bus, RS232, RS485, and 1-Wire.

The RTCU LX2 pro has an onboard Dual-band Multi-constellation GNSS positioning engine that supports the concurrent reception of all four global GNSS systems. The Dual-band receiver tracks not only L1 but also L5, significantly mitigating the multipath effect in an urban environment - ultimately improving positioning accuracy substantially.  The RTCU LX2 pro is also available in versions with Dead-Reckoning and RTK.

The RTCU LX2 pro improves on the RTCU MX2 turbo in several ways, most notably the LX architecture, higher performance and capacity, Bluetooth BLE, Enhanced security, and  Worldwide coverage. The RTCU LX2 pro has the same physical size and housing as the RTCU MX2 turbo and offers almost perfect hardware and software backward compatibility.
