ETRA SOM - STMP1

Processor: ST STM32MP1

ETRA SOM is the brand new solution made by DAVE Embedded Systems, based on the recent ST STM32MP1 application processor. ETRA SOM is a new solution available for the industry with particular attention to low power consumption with its ARM Dual Cortex-A7 architecture.

ETRA SOM main features:

  • Dual core ARM Cortex A7
  • pin to pin compatibility with AXEL ULite SOM based on i.MX6 UL
  • NOR SPI on board
  • NAND SLC or eMMC mass storage devices
  • Advanced security thanks to Secure Boot, Crypto Engine, etc.
  • ETHernet 10/100Mbps
  • Integrated peripheral expansion with multiple GPI/GPO/timers and keypad signals
  • Single 5V Power Supply
