A few years ago, we released a popular CAN Bus development board called CANBed. Many users have completed their own projects using this development board and shared their projects with us. We noticed that some users needed to make their own enclosure, either using 3D printing or a cardboard box.

Today, we are excited to announce the release of the CANBed with an aluminum housing. Like the original CANBed, this version features an Atmega32U4 microcontroller, MCP2515 and MCP2551 chips, and supports USB power supply or 7-28V DC input.

In the future, we will continue to release additional versions, including the RP2040 version and CAN-FD series products.
