RAK13006 WisBlock CAN Module Datasheet
Overview
Description
RAK13006 is a CAN Bus communication module based on the MCP2518FD CAN controller and ATA6563 CAN transceiver both from Microchip. The MCP2518FD is the CAN chip that communicates to WisBlock Core MCU via SPI up to 17 MHz SPI Clock Speed and ATA6563 is the low-level physical layer chip that provides a physical connection with the CAN bus communication lines. It supports both CAN 2.0B and CAN FD with an arbitration bit rate up to 1 Mbps. This WisBlock Interface module is ideal for industrial and automotive applications.
Features
- Based on MCP2518FD and ATA6563
- Arbitration Bit Rate up to 1 Mbps
- ISO11898-2:2016 and SAEJ2962-2 Compliant
- Configurable terminal resistance on CANH and CANL lines via slide switch
- Operating temperature: -40 °C ~ 85 °C
- Size: 25 x 35 mm
Specifications
Overview
Mounting
The RAK13006 module can be mounted on the IO Slot of a WisBlock Base board. Figure 1 shows the mounting mechanism of the RAK13006 on a WisBlock Base board, such as the RAK5005-O, and Figure 2 shows the terminal crimp connector.
