Product Description
CANBed Dual is a CAN Bus development board with 2 independent CAN FD interfaces based on RP2040. RP2040 has 2MB of Flash and 264KB of RAM. The operating frequency is up to 133MHz, which is suitable for most embedded applications.
Features
Here is a new member of the CAN Bus family in Seeed, let's shed some light on CANBed DUAL!
CANBed DUAL, a CAN Bus development board, is based on the RP2040 chip which is the debut microcontroller from Raspberry Pi. It brings signature values of high performance, low cost, and ease of use to the microcontroller space. There are 264 KB of SRAM and 2MB of Flash memory on board. The operating frequency is up to 133MHz, and it contains a 6PIN Terminal and a flexible Micro USB connector where you can either program the board or supply power to the board. The voltage input range is 9-28V which provides a stable 5V/1A output. There are also rich interfaces on board including one I2C, one UART, one SPI interface, three analog input interfaces, and eight digital IO
CANBed DUAL has two independent CAN Bus interfaces which are CAN2.0 and CAN FD, and it uses high-performance CAN Bus chip MCP2515 as CAN2.0 controller and MC2517FD as CAN FD controller. With CANBed Dual, you can learn CAN Bus communication, build product prototypes and read the data from the car. Also, as a part of your product, it integrates the processes of designing the MCU and the CAN Bus, and you only need to complete other hardware designs.
What is CAN-BUS?
CAN stands for Controller Area Network, it is used to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer which allows for control and data acquisition. These devices are also called Electronic Control Units (ECU) and they enable communication between all parts of a vehicle.
Today, you can find up to 70 ECUs in a modern car. CAN is a serial communication bus designed for industrial and automotive applications. For example, they are found in vehicles, farming equipment, industrial environments, etc.
How does CAN-BUS work?
The fuel level, door sensors, odometer, and many more parts of a car have to communicate with each other somehow, and CAN BUS is what they used to do. These CAN-compatible components, called “nodes” are connected with a 3-string copper wire, with no central router to govern the data flow. Every node can hear the messages of every other node.
Every node has an ID, where the ones with the higher priority ID can have the priority to “talk” first while the others “listen”. This is to ensure that there are never two nodes talking at the same time. The most significant benefit of CAN-BUS is to be able to just connect components without having to worry about signal routing.
