AI-generated concept placeholder for an ESP32-based CAN-FD gateway; component placement and connector details are illustrative, not a finished board design.
Note
This is purely a concept. The image above is an AI-generated illustration of the idea. The only reason I’m putting it here is because I have every intention of developing it further.
As mentioned in the goals section, I like telemetry. I have every intention of getting metrics from the various components in this system exported to some sort of time-series database for analysis and visualization.
This almost certainly will be a basic board with nothing more than an ESP32 and CAN-FD interface.
Why an ESP32 and not STM32 like the rest of the system?
Because I don’t see the gateway as a core part of the system. It’s more of a really really useful accessory.
At least initially, I will likely go with an ESPHome-based solution because that makes it trivial to get telemetry data exposed to a time-series database via MQTT or HTTP and also makes HomeAssistant integration seamless.
