For customers wanting to do custom CAN bus enabled sensors and widgets we’ve always recommended they “Get an Arudino + CAN bus shield. Oh, and also get an automotive-grade power supply”. We got tired of seeing these messes of boards and wires in harsh automotive environments, so we came out with a fun development board specifically designed for this task.
Our ESP32-CAN-X2 features the powerful ESP32-S3 with 8MB flash / 8MB RAM, TWO CAN bus ports, and an automotive-grade power supply, to protect against the harsh electrical system you’ll find in cars.
You’ll have endless possibilities:
- Create a button panel to broadcast messages to your PDM
- Trigger a relay (with additional support circuitry) via a CAN bus message
- Illuminate LEDs and indicators based on CAN bus messages
- Bridge two CAN bus networks with different baud rates
- Collect data from two different CAN bus networks with different baud rates
- Isolate traffic between CAN networks
- Create a “man in the middle” agent, which will help identify the source of CAN messages, helpful for CAN bus reverse-engineering efforts
- And much more – starter Arduino and circuitpython projects on our wiki will help you get going quickly.
Hello , i recieved this one. Currently could not detect port No.
Of couse i already installed “CP210xVCPInstaller_x64”.
Could you tell me countermeasure,please?
Hi, please follow the instructions here for flashing the Arduino example. https://wiki.autosportlabs.com/ESP32-CAN-X2#Step_by_step_instruction_for_Arduino_IDE
Note, when you plug the device into USB, hold the “BOOT” button down first; this will put the device into bootloader mode and then should be seen on your computer.
Hello , Thank you for quickly reply.
i can see com port . Thanks!
i will make some sketch.
