HAT 2 isolated relays CAN

Features:

Adopts MCP2515 and SN65HVD230 dual-chip combined solution, enables 2-channel CAN communication
Built-in electrical isolation, providing stable isolated voltage, no additional power supply required for isolated terminal
Built-in digital isolator, signal isolation makes communication more secure, more stable and better anti-interference
On-board TVS (Transient Voltage Suppressor) diode, provides ESD protection and transient overvoltage protection
On-board voltage translator, select 3.3 V / 5 V operating voltage by jumper
On-board 120 Ω terminal resistor, configured by jumper
SPI control pins, for connection with host control boards such as STM32 / Arduino
