Description

The Autosport Labs Dual CAN Bus Automotive Grade Development Board is designed to make CAN bus communications easy for automotive and industrial applications.

What's Included:

• ESP32-CAN-X2 development board
• 6 pin JST-PH pigtail for power, ground, CAN1, and CAN2 connections
• Two 40 pin male headers for breadboard use

It features the ESP32-S3-WROOM-1-N8R8 using an Xtensa® 32-bit LX7 CPU operating at up to 240 MHz (8MB flash, 8MB PSRAM), dual CAN bus support, two CAN bus transceivers, and an automotive-grade power supply to safely integrate it into your car project.
All IO pins are broken out to a breadboard-friendly layout so you can easily integrate it into bigger projects. A separate connector also provides power, ground, and dual CAN connections so you can quickly wire it into CAN networks.


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

Features

• ESP32-S3-WROOM-1-N8R8 microcontroller powerful dual-core Xtensa LX6 CPU running at up to 240 MHz.
• Automotive grade power supply: Ruggedized power supply up to 40v input, provides safety for automotive applications where damaging voltage surges and load dumps are
• Pin Headers: All available GPIO pins are broken out to the pin headers on the board for easy interfacing and programming. For details, please see our documentation
• USB-C port: A USB-C port supplies power for programming, flashing your code, communications using the USB 1.1 specification, and also provides JTAG debugging.
• Boot Button: Firmware download button. Holding down **Boot** and then pressing **Reset** initiates Firmware Download mode for installing firmware.
• Reset Button: Resets the device
• LED: User controllable LED; use it to indicate status or anything else you would like.
• Power LED: Turns on when power is connected to the board.
• Power / CAN headers: 6 pin JST-PH header provides 12v (nominal) power, ground, CAN1 and CAN2 connections.
• CAN termination jumpers: 2 CAN termination jumpers are provided, default enabled with 120 ohm termination
• Built-in CAN transceivers: Dual CAN transceivers are included on board.
• 2nd CAN bus provided by MCP2515: while CAN1 uses the built in TWAI CAN compatible controller; CAN2 uses the on-board MCP2515 CAN bus controller.
