SQM4-K66 is a solderable computer module based on NXP Kinetis K66 microcontroller with ARM® Cortex®-M4F core. It runs at up to 180 MHz and consumes as little as 500mW.

The integrated Ethernet PHY provides 10/100 Mbit Ethernet connection with time stamp functionality. Together with 2x USB interfaces and on-chip Flash memory, this module is suitable for high-performance real-time applications with Ethernet and USB connectivity. Customers can mainly find it useful for proof-of-concept applications, rapid prototyping or small series production.

The module is offered in two variants:

  • SQM4-K66-F features a 32 KB SPI FRAM memory.
  • SQM4-K66-M features a 4 MB SPI NOR FLASH memory.

The Kinetis K66 series is well supported by a wide range of RTOS systems, e.g. FreeRTOS. Bare metal routines are supported as well, e.g. KSDK.
