CANgineBerry - CANopen Module for Raspberry Pi

The CANgineBerry for CANopen is an active CAN Bus co-processor module that uses a regular UART communication channel towards the host system. With its independent 32-bit microcontroller, the CANgineBerry can easily execute CAN Bus protocols with tough timing demands such as CANcrypt or CANopen with response times of under 10 ms.

PiCAN FD Zero - CAN FD HAT for Raspberry Pi Zero with 1A SMPS

The PiCAN FD Zero HAT provides CAN Bus FD capability for the Raspberry Pi Zero. It uses the Microchip MCP2518FD CAN controller with MCP2562FD CAN transceiver. Connection is made via a 4way plug-in terminal block. CAN_H, CAN_L signals, and +12 VDC supply for the board and the Pi Zero. Onboard is a 1A SMPS that supplies power to the PiCAN FD and Pi Zero board.
