Features at a glance
  • Adopts MCP2515 and SN65HVD230 dual chips combined solution, allows 2-channel CAN communication
  • Integrated power isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal
  • Onboard digital isolator, signal isolation makes the communication more safe, more stable, and better anti-interference
  • Onboard TVS (Transient Voltage Suppressor) diode, provides ESD protection and transient peak voltage protection
  • Onboard voltage translator, select 3.3V/5V operating voltage by jumper
  • Onboard 120Ω terminal resistor, configured by jumper
  • Breakout SPI control pins, for connecting with host control boards like STM32/Arduino
