The OPOS6UL_NANO: a perfect i.MX6UL processor board for low cost embedded Linux systems with reduced mechanical constraints


The OPOS6UL_NANO is the new Armadeus system's industrial SOM (OposSOM family). It is today the most compact industrial solution when considering system as a whole. This module benefits from a competitive price/performance and a product life cycle of 10 years. Automotive qualification is in progress.

Fitted with a 528 or 696 MHz i.MX6UL processor, 256 or 512 MB DDR3 RAM, 4GB eMMC, a 10/100Mbits Ethernet port including PHY, two USB2.0 OTG ports including PHY, and an optional Wi-Fi/Bluetooth module (BLE compliant), the OPOS6UL_NANO is ideal for space constraint systems like IoT, Drone and portable devices.

Note: Armadeus systems provides a complete Open Software Development Kit for Linux Host PC. All tools are included: cross-compiler, cross-debugger (no JTAG/BDI required), lots of examples. This SDK is able to generate Linux, NuttX or bare-metal applications for your OPOS6UL_NANO.
