CANduino v4 with ATmega328P, MCP25625 (MCP2515 and MCP2551) and CH2102 chip.

The CANduino v4 is based on the well-known Arduino Nano and adds via the CAN-Controller/-Transceiver MCP25625 the possibility of communicating via CAN bus. A big advantage is the small form factor and the possibility of programming via a USB-C interface.

Via two jumpers the CAN-Controller can be deactivated and a 120 ohm resistor can be connected in parallel as a terminating resistor between CAN high and CAN low. By default, the jumpers are connected.

Please note that the CAN controller uses the pins D2, D10, D11, D12 and D13 and that these can accordingly not be used or only to a limited extent when the CAN bus is active!

If the CANduino is not showing up on your computer, please download the driver for the CP2102 which can be found here: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads

The CAN-Bus library we would recommend to use with the CANduino (especially when using the CAN bus for the first time) can be found here (along with some example sketches): https://github.com/MassiveButDynamic/CANduino

We also sell a BreakOut module for the CANduino v4 with screw terminals.
