Arduino Portenta Breakout is a new breakout board from Arduino Pro, to expand the developing, testing and debugging capabilities of Portenta family boards. Portenta is a family of industry-ready products from Arduino, the open source hardware company. The Portenta H7 was their first product. The new breakout board allows the high density pins to be wired out as standard pin headers and connectors. This will allow engineers to easily work with different IOs and interfaces of the high performance STM32H747XI host processor.

The new breakout board includes a header to interface OpenMV Global Shutter Camera Module directly to the board. This allows the rapid development of machine vision applications leveraging the power of Portenta H7. The other features include,

  • Power ON button
  • Boot mode DIP switch
  • Connectors
    • USBA
    • RJ45 GBit Ethernet
    • MicroSD card
    • OpenMV shutter module
    • MIPI 20T JTAG with trace capability
  • Power
    • CR2032 RTC lithium battery backup
    • External power terminal block
  • I/O
    • Break out all Portenta high density connector signals
    • Male/female HD connectors for interposing breakout between Portenta and shield to debug signals
