ADLINK LEC-RB5 – A Qualcomm QRB5165 SMARC module designed for drones and robots

ADLINK Technology LEC-RB5 is a SMARC compliant system-on-module powered by the Qualcomm QRB5165 octa-core Cortex-A77 class processor which we’ve already seen in Qualcomm Flight RB5 high-end drone reference design and Lantronix Open-Q 5165RB system-on-module designed for robotics applications.

The LEC-RB5 SMARC module ships with up to 8GB PoP LPDDR4 memory, 256GB UFS storage, provides on-device artificial intelligence capabilities (up to 15 TOPS), support for up to 6 cameras, and low power consumption. The main target applications are high-end robots and drones in the consumer, enterprise, defense, industrial, and logistics sectors.

LEC-RB5 block diagram

ADLINK offers support for Ubuntu and Yocto Linux, as well as the “LEC-RB5 DevKit” with 4GB LPDDR4 memory, 64GB UFS storage, and an AC/DC power adapter. I think it’s the first time I see a SMARC module with built-in MIPI CSI connectors soldered on the device, instead of being available via the MXM edge connector. The LEC-RB5 is quite larger than the Lantronix Open-Q 5165RB (50 x 29 mm) module but for applications relying on four cameras, the complete system may not be much larger or heavier since the carrier board does not need to handle the camera part.

ADLINK LEC-RB5 SMARC module with Qualcomm QRB5165 is most likely not available just yet, as everything is shown as being “Preliminary”. Visit the product page for further details.
