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 120O terminal resistor, configured by jumper
- Breakout SPI control pins, for connecting with host control boards like STM32/Arduino
