Compulab part number

FT.Q_CAN

Description

TEL-CANBUS provides a CANbus interface with isolation through a DB-9 connector.

  • Single CAN device
  • Supports CAN 2.0A Specifications.
  • Up too 1Mbit/s bit rate.


ToDo: CANbus version?
ToDo: Data rate?

TEL-CANBUS is utilizing a USB2 interface. Multiple TEL-CANBUS cards can be installed in a system.

Features

  • CANbus through DB-9 Connector
  • Implimented using STM32F042C6 MCU
ToDo: single CANbus device or multiple? More information about CANbus capabilities
ToDo: microcontroller? Which?

Software

  • Windows and Linux support
    • Driverless operation in Windows
    • USB native device in Linux

Electrical and environmental

  • Isolation per UL 1577
  • Transient immunity: 30kV/uS.
  • Isolated DC 5V power
  • Ambient Operation from –40°C to 85°C.

Configuration

  • Two Code implementations in one device switchable by a DIP Switch.
  • Defult CANable USB CDC implementation & candleLight USB device implimintation.
ToDo: please elaborate what are the code implementations
  • DIP switch for enabling/disabling on-board 120 Ohm termination
ToDo: can the firmware be upgraded? How?
  • Upgradeable using build-in MCU bootloader and openly available tools. (Please follow update guide in GitHub)

Open source hardware and software

  • Complete hardware design files are available
  • Complete firmware is available
  • Designed for Hacking - Easily scriptable Python SW library for easy and cross-platform communication to the device
