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 up to 64 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.

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.
