商品說明

CANBed-Arduino CAN-BUS 開發套件 (帶有CAN-BUS的ATmega32U開發板)

CANBed – Arduino CAN-BUS 開發套件內嵌了 ATmega32U4 芯片，這意味著您不需要在另一個 Arduino 板上添加其他跳線，它是一塊Arduino開發板本身加上 MCP2515 CAN 總線控制器和 MCP2551 CAN 總線收發器！CAN-BUS是一種通用協議，因其傳輸距離遠、通信速度中等、可靠性高而在工業中得到廣泛應用。現在你可以通過這個小小的開發板實現一個 CAN-BUS 項目。由於板載ATmega32U4芯片，該板的管腳資源豐富。事實上，板上基於核心芯片設置的引腳有18個，包括數字引腳、模擬引腳、UART和I2C接口。此外，該CANBed採用帶SPI接口的MCP2515 CAN總線控制器和MCP2551來實現CAN-Bus能力。還有兩種CAN總線接口可滿足各種需求，即sub-D9連接器和接線端子接口。它們將滿足您在連接方法中的所有需求。這款 CAN-Bus 開發板與 Arduino IDE 完美相容。借助 Arduino CAN-Bus 庫，您將為 CAN 項目節省大量時間。

Description

CANBed – Arduino CAN-BUS Development Kit embeds an ATmega32U4 chip, which means you don’t need to add other jump wires to another Arduino Board, it is an Arduino board itself plus MCP2515 CAN Bus controller and MCP2551 CAN Bus transceiver!

CAN-BUS is a common protocol and widely used in industry due to its long travel distance, medium communication speed, and high reliability. Now you can realize a CAN-BUS project through this tiny little development board.

Because of the ATmega32U4 onboard chip, this board has rich resources in pins. As a matter of fact, there are 18 pins based on core chip set up on the board, which include digital pins, analog pins, UART, and an I2C interface. Besides, this CANBed adopts MCP2515 CAN Bus controller with SPI interface and MCP2551 to achieve the CAN-Bus capability. There are also two kinds of CAN Bus interfaces for various demands which are sub-D9 connector and terminal block interface. They would fit all your needs in the connecting method.

This CAN-Bus development board is perfectly compatible with Arduino IDE. With the help of the Arduino CAN-Bus library, you will save plenty of time for your CAN project.

Hardware Overview

1.9×2 IO Pin OUT: The IO of Atmega32U4 is listed out here

2.ATmega32U4 Chip:

The master of the entire module is mainly used to store data on the TF card or transfer data to the computer through the type C cable. In addition, since it’s Arduino compatible, you can use it to implement some simple controls, such as triggering a buzzer alarm when the speed exceeds a certain value.
