System-on-module with microcontroller Kinetis K70 from the SQM^® modules serie. Besides the ARM Cortex M4 microcontroller with 1 MB on-chip memory it disposes of a 128 MB DDR2 SDRAM memory, 128 MB FLASH memory, Wi-Fi modem, Ethernet, USB and a wide range of other peripherals connectable via 135 GPIO. Quick and easy development is ensured by a JTAG connector. All this compressed on 16 cm² only.

The module is placed on a thin ledge allowing the parts placement on both sides. Together with a high degree of integration it minimizes the module size, giving also an option to use the surface of motherboard for other (hidden) components. Rapid simplification of the motherboard circuits leads to usability of cheaper production technology and hence a significant price cut. The module is intended to be soldered directly on the board using the RIM connection, providing 4 ways of assemblage (bottom, top, mirrored bottom, mirrored top).

For quick start with the SQM4-K70 module we recommend to use EasyBoard, a development board expanding the most of the peripherals available on the module. The board itself illustrates how usage of SQM4 modules serie allows to produce full-fledged embedded device on simple two-layer board.
