AI Gateway combines Raspberry Pi Compute Module 4 with Google Coral Edge TPU

Techbase quickly unveiled an update to their Modberry industrial controllers with Modberry 500 CM4 DIN Rail computer as soon as Raspberry Pi Compute Module 4 was launched.

The company has now introduced another Raspberry Pi CM4 based product with ModBerry AI GATEWAY 9500-CM4 gateway combining the Broadcom BCM2711C0 system-on-module to Google Edge TPU to cater to applications leveraging AI acceleration.

Modberry AI-Gateway-9500-CM4ModBerry AI GATEWAY 9500-CM4 preliminary specifications:

  • SoM – Raspberry Pi Compute Module 4
  • AI accelerator – Google Coral Edge TPU module with up to 4 TOPS connected over the RPi CM4’s PCIe interface
  • Peripherals (customizable as needed)
    • USB, HDMI, and Ethernet.
    • Serial RS-232/485 ports
    • Digital and analog I/Os with or without opto-isolation
    • Relays,

  • PCIe modules for wireless support
    • Cellular – 4G/LTE and 5G modem, interchangeable with Coral TPU, plus on-board eSIM
    • LPWAN – NB-IoT, LoRa, Sigfox, Wireless M-Bus
    • ZigBee
    • Additional Wi-Fi/Bluetooth interface or Wi-Fi Hi-Power
    • Custom wireless interfaces
  • Misc – Reset and software update pinholes, LEDs, optional accelerometer, OLED screen, SuperCap backup power support.
  • Security – Optional TPM security chip
  • DIN-Rail enclosure

Raspberry Pi 4 AI Gateway-Google Coral Edge TPUTechbase explains the Coral AI accelerator can easily be used in Linux with Raspberry Pi Computer Module 4 with full support for TensorFlow Lite framework and AutoML Vision Edge solution. The company also mentions this works in Windows, which I suppose means Windows 10 IoT.

ModBerry AI GATEWAY 9500-CM4 is not quite available yet, but Techbase says delivery time for various configurations will be around 2 months. There’s not much for information at this stage, and interested parties are invited to submit their requirements via IIoT shop.
