Castellated Dreams Delivers Compact, Surface-Mountable CAN Bus Module

Electronics design company Castellated Dreams has launched a compact and versatile module to add CAN bus connectivity to various projects. Built on the Microchip MCP2515 controller, the module connects to host devices using SPI communication and offers a dual-purpose design suitable for breadboard testing, manual wiring, and surface-mount applications.

Castellated Dreams states,

“This module is based on the reliable MCP2515 chip interfaced via SPI. Its breadboard-friendly design makes testing solutions effortless before final integration, while the castellated holes allow it to be directly soldered onto a PCB for faster and simpler implementation.” The module’s flexibility makes it suitable for hobbyists, prototypers, and professionals working on advanced applications.

The idea for this module stems from Castellated Dreams’ experience developing solutions for robotics, including Mars rover-inspired vehicles, underwater systems, and rocketry. The design team recognized that existing CAN bus modules were often bulky and cumbersome, forcing users to redesign their systems or use inefficient alternatives. This new module addresses these issues by prioritizing compactness and ease of integration.

Measuring just 17.8×16.5mm (approximately 0.7×0.65″), the module occupies about a quarter of the space of comparable designs, making it ideal for projects with size constraints. The module brings all connections, including SPI and CAN, to castellated headers. Users can attach standard 0.1″ pins for breadboard use, opt for manual wiring, or solder the module directly onto a custom PCB as a surface-mount component.

Beyond its physical design, the module stands out for its adaptability across various scenarios. The compact size and robust features make it suitable for prototypes and production environments alike. Its reliable performance and ease of integration streamline workflows, saving time and effort for developers.

Castellated Dreams is currently offering this CAN bus module on Tindie for $28.50. For added convenience, buyers can include headers for an additional $2, available either unsoldered or pre-soldered.

This module is a game-changer for anyone seeking a small, efficient solution for CAN bus integration, particularly in space-constrained or high-precision environments. It balances compactness, reliability, and flexibility, making it an invaluable tool for developers across various fields.
