With a transmission rate of approximately 1Mbps, the bus frequency is set and synchronized among all connected devices. Each node on the network has a unique address, allowing it to selectively listen to messages intended for it. Adding new nodes to the network is simple, requiring only a connection to the shared data lines. Thanks to clever data encoding, message collisions are detected, and retransmissions occur to ensure reliable communication.
The Adafruit CAN Bus FeatherWing features the MCP2515 controller, a widely supported and popular chipset with Arduino and Circuit Python drivers. It only requires an SPI port and two pins for chip-select and IRQ. Adafruit CAN Bus FeatherWing – MCP2515 FeatherWing enables seamless transmission and reception of messages in both standard and extended formats, with a maximum data rate of 1 Mbps. Upgrade your Feather board with the Adafruit CAN Bus FeatherWing and unlock the potential for high-speed, reliable communication in your projects.
Features:
- MCP2515 Controller: Popular and well-supported chipset, compatible with Arduino and CircuitPython.
- 5V Charge-Pump: Generates 5V from a 3.3V Feather board to power the transceiver.
