This board connects a 3.3V microcontroller to a CAN bus. It takes the TX and RX lines from your MCU's CAN controller and drives the CANH/CANL differential pair used on industrial, robotics and automotive networks.

The transceiver is a Texas Instruments SN65HVD230, built for the ISO 11898 high-speed CAN standard. It runs from 3.3V, so it connects directly to STM32, ESP32 (TWAI) and other MCUs with a built-in CAN controller without level shifting or a 5V supply. It is a lower-power, footprint-compatible replacement for the PCA82C250, and can share a bus with 5V CAN transceivers.

To wire it up, connect 3.3V and GND, connect CAN TX and CAN RX to your controller's CAN pins, then connect your twisted pair to the CANH and CANL screw terminals. A CAN bus needs 120Ω termination at each end of the line.

Features

  • Runs from a 3.0 to 3.6V supply, so it connects directly to 3.3V microcontrollers
  • Over 16kV HBM ESD protection on the bus pins, plus thermal shutdown
  • High input impedance supports up to 120 nodes on one bus
  • Glitch-free power-up and power-down for hot-plugging, and an unpowered node does not load the bus
  • Signalling rates up to 1Mbps
  • Open-circuit fail-safe receiver that holds a known output state if the bus wires are disconnected
  • 4-pin header for the MCU and a 2-position screw terminal for CANH/CANL
  • Pre-soldered 120-ohm termination resistor
