The DFRobot Gravity: CAN to TTL Communication Module w/ SLCAN Protocol is a sophisticated communication module that facilitates CAN-to-UART and USB 1.0 communication. It is designed to be compatible with both 3.3 V and 5 V, and supports the CAN 2.0 protocol. The module incorporates the SLCAN command, which simplifies the process of engaging in CAN data transmission and configuring its functionalities by merely sending AT commands.
This advanced module not only provides a UART interface but also integrates a USB interface. This integration eliminates the need for complex conversions between USB and UART during data debugging. When connected to a computer via USB, it allows for efficient data debugging through a serial assistant, which is particularly useful when the module is used on-site for debugging.
The module boasts a configurable CAN baud rate range of 25 K - 1 Mbps. It supports a maximum rate of 2 milliseconds per transmission, ensuring the delivery of 500 data packets per second without any loss. This reliable communication capability significantly minimizes the potential for errors in your project and simplifies the project debugging process.

The module is also equipped with data communication indicators and a 120Ω resistor jumper, which are designed to enhance the efficiency of project development and validation.
This module is designed for use by robotics and intelligent vehicle enthusiasts, research and development engineers, and small-scale development companies. It is suitable for learning, product testing, development, and integration purposes. It can also be utilized in the illumination control system for small vehicles.
The module operates at a voltage of 3.3 V - 5 V and a current of 65 mA. It utilizes the SLCAN AT command protocol and is compatible with the CAN 2.0 protocol. The USB interface is USB 1.0 and the UART interface voltage levels are 3.3 V, 5 V. The UART baud rate is 115200 Bps (default configuration). The module supports various optional CAN communication baud rates and comes with a CAN communication jumper and a CAN communication indicator. It supports programming languages such as C++, Arduino C, and Serial Assistant. The solder material used is environmentally friendly lead-free solder.

Refund Policy
If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.
This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.
Please review the Return Conditions, Return Exceptions and the process on How to Request a Return Authorisation (RA) before initiating a return request.
United Kingdom consumers exercising their statutory Right of Cancellation are subject to different conditions. See the Statutory Right of Cancellation.
Returns under this policy concern non-defective products. In the case of a confirmed manufacturing defect, remedies are handled under the Warranty terms, at the Vendor's discretion. See the Warranty section.
Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorisation (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A £100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tyres, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odour-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
- Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
