AL Pi-Tron CM4

Compact Box-PC, Broadcom BCM2711, 4x Arm® Cortex®-A72 @1.5 GHz
  • Memory: LPDDR4-RAM, Compute Modul CM4 Lite, 1x microSD Card Slot, FRAM
  • Communication: Ethernet, USB, RS232, RS485, CAN, DIO, WLAN/Bluetooth
  • Operating system: Raspbian Linux (not preinstalled)

The Pi-Tron CM4 is based on the new fourth-generation Compute Module and features the Broadcom BCM2711 4x Arm® Cortex®-A72, 64-bit SoC @1.5 GHz, a significantly faster processor than the previous generation. It has more memory with 1 GB, 2 GB, 4 GB or 8 GB LPDDR4-3200 SDRAM, depending on the variant. There are also options for an eMMC memory with 8 GB, 16 GB or 32 GB available. Additionally, the board offers an optional pre-certified wireless LAN/Bluetooth connection.

An M.2 B key slot with PCIe connection enables the use of standard modules with the corresponding interface. For example, individual AI solutions for machine vision and machine/deep learning can be implemented with the very powerful Hailo-8™ AI modules or the Google Coral AI Edge TPU. For the integration into IoT solutions, the Pi-Tron has been prepared to use LTE modules with SIM cards and an external antenna connection. 

The range of functions of the interfaces has been significantly expanded. The Automation Line AL Pi-Tron CM4 is available in a housing, allowing for universal application and making it especially well-suited for industrial applications.
