SOM

 

STM32F7 System-On-Module

 

The Emcraft Systems STM32F7 System-On-Module (SOM) is a compact (30 mm x 46 mm) STM32F7 mezzanine module that combines a 216 MHz 32-bit ARM Cortex-M7 processor core with 32 MB SDRAM, 16 MB NOR Flash and an Ethernet PHY on a single board. The SOM interfaces to a baseboard (motherboard) using two 80-pin interface connectors.

Emcraft develops and maintains a Linux software distribution for the STM32F7 SOM, including Linux (uClinux) BSP (Board Support Package), U-Boot firmware and a Linux-hosted cross-development software environment.

 

Starter Kit

 

STM32F7 SOM Starter Kit



The STM32F7 SOM starter kit (KIT-STM32F7-EXT) provides a cost-efficient hardware platform enabling development of Linux applications using the STmicroelectronics STM32F7 devices. The kit includes the STM32F7 System-on-Module, a SOM-BSB-EXT development baseboard, and a mini-USB cable for USB-based power and serial console.

The baseboard is 100x70 mm in size and has the following main interfaces:

  • USB interface using USB-UART bridge connected to UART of the STM32F7
  • 10/100 Ethernet interface and RJ-45 connector
  • USB OTG Interface and mini-USB connector
  • Standard 20-pin ARM JTAG interface
  • User LEDs and push-button
  • Unused STM32F7 signals available on a breadboard area.

STM32F7 SOM Design Kit

 


For those customers who have successfully evaluated the STM32F7 System-On-Module and would like to proceed with designing the SOM into embedded product, Emcraft System provides the STM32F7 SOM Design Kit.

The STM32F7 SOM Design Kit is an advanced product, separate from the STM32F7 SOM Starter Kit.

The kit is comprised of the following materials and services:
  • The STM32F7 System-On-Module (SOM) schematics (PDF file only). The package is provided as an advanced hardware material allowing hardware designers to understand subtle points of the SOM implementation and interface.
  • Suggested STM32F7 SOM to baseboard mapping (Excel file). Upon purchase of the kit, you will be able to send a list of I/O requirements for your application to Emcraft. Emcraft will review and return an Excel file with recommended mapping of I/O interfaces from the SOM to your custom baseboard.
  • 1 (one) review of your custom STM32F7 SOM baseboard schematics (SOM interface section only), with detailed comments returned over email.
