CANBed - Arduino CAN-BUS Development Kit (Atmega32U4 with MCP2515 and MCP2551)

NoteWe have already released CAN-BUS Shield V2 which is an Arduino shield based on CAN-BUS. This CANBed - Arduino CAN-BUS Development Kit carries an Arduino chip - Atmega32U4, which means it combines the CAN-BUS Shield and Arduino Development Board together on one single board.Key FeaturesAtmega32U4 with Arduino Leonardo bootloader on the boardMCP2515 CAN Bus controller and MCP2551 CAN Bus transceiverOBD-II and CAN standard pinout selectable at sub-D connectorCompatible with Arduino IDEDescriptionCAN-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 tinny little development board. Different from CAN-BUS shield series that we have released, CANBed - Arduino CAB Bus Development Kit embed an Atmega32U4 chip, which means you don¡¯t need to add other jump wires to another Arduino Board, it is an Arduino board itself!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 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 interface for various demands which are sub-D9 connector and terminal block interface. They would fit all your need 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.SpecificationParameter ValueMCU Atmega32U4(with Arduino Leonardo bootloader)Clock Speed 16MHzFlash Memory 32KBSRAM 2.5KBEEPROM 1KBOperate Voltage(CAN-BUS) 9-28VOperate Voltage (MicoUSB) 5VInput Interface sub-DHardware Overview1.9x2 IO Pin OUT:The IO of Atmega32U4 is listed out here2.Atmega32U4:The master of the entire module mainly used to store data on the TF card or transfer data to the computer through the type C cable.
