Introduction

This module is based on the reliable MCP2515 chip which is interfaced using SPI. With its breadboard-friendly design, you can easily test your solutions before integrating them into your main system. The castellated holes allow the module to be soldered directly onto another PCB, making implementation faster and easier. This makes it an ideal choice for hobby projects, prototyping, and even more advanced applications.

Over the past few years, we've been involved in various student projects including underwater robotics, Mars rovers, and hobby rockets. All these projects required communication between system nodes. We found existing CAN bus solutions to be large and cumbersome, often lacking good fastening options and to be incompatible with our preferred connectors. Driven by the idea to streamline upcoming projects, we created this small-sized module with castellated holes to address these challenges.

Features

• Compact Size: Measuring just 1.78 cm x 1.65 cm, this module is a quarter the size of typical alternatives, providing you with more flexibility in your project designs.
• Castellated Holes: These versatile holes allow for both breadboard use and direct soldering to another development board, giving you multiple implementation options.
• Connector Flexibility: The castellated hole design also lets you choose your connector of preference, ensuring seamless integration with the rest of your system.
• SPI interface: Communicate with the MCP2515 chip over SPI. More information can be found in the MCP2515 datasheets and varous sources online
• Power indicator LED: An LED indicates if the board has power
• 120Ω termination: A solder jumper allows you terminate the bus with a 120Ω resistor

See this awesome tutorial from Last Minute ENGINEERS on how to implement the device with Arduino. The tutorial uses another CAN bus module that is also based on the MCP2515 chip, so the steps should be the same as the Castellated Dreams Micro MCP2515 CAN-bus Castellated Module https://lastminuteengineers.com/mcp2515-can-module-arduino-tutorial
