Key Features​

  • CAN Bus Advantages: Long-distance data transmission, strong anti-interference capability, high real-time performance, and high reliability.
  • Model Description:
    • FLY-UTOC 1: Supports connection of four CAN devices to the bus.
    • FLY-UTOC 3: Based on UTOC 1, it additionally provides two USB female ports. These can be used to connect devices that do not have an integrated CAN transceiver but whose main control chip has CAN controller functionality (for example, by directly connecting the physical pins of the motherboard's USB interface to the CAN TX/RX pins of the main control chip to achieve CAN communication).

Product Specifications​

  • Main Control Chip: STM32F072 / APM32F072
  • Logic Voltage: DC 3.3V
  • USB Communication Interface: USB Type-C, for connecting to the host computer only
  • Power Supply and Interfaces:
    • FLY-UTOC 1:
      • Two XH2.54-4P interfaces (CAN interfaces, capable of providing 5V power externally)
      • Two POWER terminal blocks, supporting 12–24V DC input (used to power external CAN devices; the module itself does not require a separate power connection)
    • FLY-UTOC 3:
      • Based on UTOC 1, adds two USB female ports
  • Terminal Resistor: Onboard 120Ω terminal resistor, no jumper or external connection required
