Adafruit CAN Bus FeatherWing - MCP2515 Spedizione:4-6 Giorni which operate from 5 to

which operate from 5 to 28 V and can deliver a continuous 3 A per channel (up to 5 A per channel for a few seconds)

You will need to remove the XBee module while reprogramming over serial

FTDI Friend (great for any OS)

which means a powerful microcontroller such as the ESP32-S3 with octal PSRAM or a computer like a Raspberry Pi (with either direct-DPI connection or an intermediary chip like the ICN6211)

Adafruit CAN Bus FeatherWing - MCP2515 Spedizione:4-6 Giorni which operate from 5 toCAN Bus is a small scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C, and don't have the pins or computational ability to talk on Ethernet. CAN is 2 wire differential, which means it's good for long distances and noisy environments. Messages are sent at about 1Mbps rate you set the frequency for the bus and then all 'joiners'
