Portenta H7 Lite Connected brings back WiFi & Bluetooth

Arduino has launched another Arduino Pro board! Well, sort of. Let’s not get too excited. The Portenta H7 Lite Connected is based on last month’s Portenta H7 Lite that itself was a cost-optimized version of Portenta H7 board without a wireless module, USB-C video output, and only fitted with the lower cost Microchip ATECC608 secure element.

Portenta H7 Lite Connected is exactly the same board, except it brings back the Murata 1DX module with 2.4GHz 802.11b/g/n WiFI 4 and Bluetooth 5.1 BR/EDR/LE connectivity, plus the related u.FL antenna connector.

Portenta H7 Lite Connected specifications:

  • Microcontroller – STMicro STM32H747XI Cortex-M7 @ 480 MHz + M4 @ 200 MHz MCU  with 2MB dual-bank Flash memory, 1 MB RAM, Chrom-ART graphical hardware accelerator

  • Security – Microchip ATECC608 secure element
  • Misc – 22x timers and watchdogs
  • Power Supply
    • 5V via USB-C port or VIN pin
    • Support for 3.7V/700mAH minimum LiPo single-cell battery; integrated charger
    • Consumption – 2.95 μA in Standby mode (Backup SRAM OFF, RTC/LSE ON)
  • Temperature Range – -40 °C to +85 °C

Software support will be exactly the same as other Portenta H7 boards with programming using Arduino or MicroPython, as well as TensorFlow Lite for AI applications. The board sells for $98.40/82 Euros which compares to $72/60 Euros for the Lite version, and $103.4/89.90 Euros for the full version with video output via USB-C and NXP secure element. That means the wireless module adds 16.4 dollars or 12 Euros to the cost.

We’ll see if Arduino plans to release a “new” Portenta H7 version every month. With two remaining months to go before the end of the year, I could perfectly envision a “Portenta H7 Lite Connected Secure+” board adding NXP SE0502 crypto chip in November, and a “Portenta H7 Ultra” with 64MB RAM and 128MB SPI NOR flash in December ;).

    1. If they want a Teensy, why don’t they just work with Paul? He manages to make better boards for less even in small volumes.

      (Also,somethingisbrokenasIcan’ttypespaces,Ihavetogobackandeditthemin!)(Also,also,thereareatonmorewebsitesrequestingscriptingthanusual!)

  1. Once again, what is the point of using STM32H7 when i.MX RT can do all this for less and faster?
