Single Board Computer OKMX6UL-C2 based on NXP iMX6UL


OKMX6UL-C2 single-board computer(SBC) to evaluate commercial-grade CPU module FETMX6UL-C1 and an industrial-grade CPU module FETMX6UL-C2, the whole board size is only 100mm x 73mm, on-board LCD, Ethernet, USB host/OTG, RTC, SD card, LED are all available. 41x GPIO pinned out by dual-row pin connectors with pitch of 2.54mm, which is very convenient for usrs to flash OS and test the board to finish their evaluation.

The OKMX6UL-C2 SBC is based on NXP Cortex-A7 low power featuring processor iMX6UL @ 528MHz. Adopt SoM + Carrier Board structure, while SoM is only 40*50mm, widely used in automotive, communication infrastructure, industrial control , smart city, smart home and other fields.

Advantage of i.MX6 UltraLite

Expanding the i.MX6 series, the i.MX6UL is a high performance, ultra-efficient processor family featuring an advanced implementation of a single Arm® Cortex®-A7 core, which operates at speeds up to 696 MHz. The i.MX6UL applications processor includes an integrated power management module that reduces the complexity of external power supply and simplifies power sequencing.

Each processor in this family provides various memory interfaces, including 16-bit LPDDR2, DDR3, DDR3L, raw and managed NAND flash, NOR flash, eMMC, Quad SPI and a wide range of other interfaces for connecting peripherals such as WLAN, Bluetooth™, GPS, displays and camera sensors.
