Description
We launched the Serial CAN Bus Module years ago, which is very practical and easy to use. Now we have slightly modified the Serial CAN Bus Module, wrote a special firmware, and launched this I2C CAN Bus Module.
我們多年前推出了串行CAN總線模塊，非常實用且易於使用。現在我們稍微修改了串行CAN總線模塊，編寫了一個特殊的固件，並推出了這個I2C CAN總線模塊。
The I2C CAN Bus Module uses I2C for communication. Default I2C Address 0x25 and Max I2C Speed of 400k.
I2C CAN 總線模塊使用 I2C 進行通信。默認 I2C 地址為 0x25，最大 I2C 速度為 400k。
The board is small and flexible, which makes it can be quickly used in any system with an I2C interface.
該板小巧靈活，可快速用於任何具有 I2C 接口的系統。
The MCP2551 is a high-speed CAN transceiver, fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551 provides differential transmit and receive capability for the CAN protocol controller and is fully compatible with the ISO-11898 standard.
MCP2551 是一種高速 CAN 收發器、容錯器件，用作 CAN 協議控制器和物理總線之間的接口。MCP2551 為 CAN 協議控制器提供差分發送和接收功能，並完全兼容 ISO-11898 標準。
The MCP2515 is a second generation stand-alone CAN controller. It is pin and function compatible with the MCP2510 and also includes upgraded features like faster throughput, databyte filtering, and support for time-triggered protocols.
MCP2515 是第二代獨立 CAN 控制器。它的引腳和功能與 MCP2510 兼容，還包括升級的功能，如更快的吞吐量、數據字節過濾和對時間觸發協議的支持。
The I2C CAN Bus Module is based on the high-performance MCP2515 CAN Bus controller and MCP2551 CAN Bus transceiver, providing a CAN Bus communication rate of up to 1Mb/s.
I2C CAN 總線模塊基於高性能 MCP2515 CAN 總線控制器和 MCP2551 CAN 總線收發器，提供高達 1Mb/s 的 CAN 總線通信速率。
In addition, there is an Atmega168PA microcontroller on the board, you can also program it through a USB to Serial board, modify the firmware or write your application directly. 此外，板上還有一個 Atmega168PA 微控制器，您也可以通過 USB 轉串口闆對其進行編程，修改固件或直接編寫您的應用程序。
There's Grove connect as well as Grove cable included in the kit, which allows connecting the module to your Arduino easily. 套件中包含 Grove 連接和 Grove 電纜，可輕鬆將模塊連接到您的 Arduino。
We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. 我們已經開發了300 多個 Grove 模塊，涵蓋了可以滿足各種需求的廣泛應用。
