SOM
The Emcraft Systems STM32H7 System-On-Module (SOM) is a compact
(30.5 mm x 40.5 mm) solderable module that combines the ST STM32H750 processor (480MHz 32-bit ARM Cortex-M7) with up to 64MB SDRAM, 64MB QSPI NOR Flash and optional 64KB EEPROM on a single board. The SOM is built onto (SMT-mounted upon) a carrier board using 120 castellated edge mounting holes (1.27 mm pitch).

Design Kit
For those customers who have successfully evaluated the STM32H7 System-On-Module and would like to proceed with designing the SOM into embedded product, Emcraft System provides the STM32H7 SOM Design Kit.
The STM32H7 SOM Design Kit is an advanced product, separate from the STM32H7 SOM Starter Kit.
The kit is comprised of the following materials and services:
- The STM32H7 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 STM32H7 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 STM32H7 SOM baseboard schematics (SOM interface section only), with detailed comments returned over email.
