Pure data signal conversion.2. Its data is stable.3. It has a green power indicator that shows the working status.4. It can monitor and maintain LIN bus device communication.Specification:Product Name: RS232 to LIN Bus ModuleProduct Chip: TJA1020Working Voltage: DC 12VWork Temperature: -25℃~85℃Work Humidity: 5%~95%RHSize: 59*31.5*17mmSpecific Function Introduction:1. The measured baud rate of the module can reach 57600bps,and the recommended maximum operating frequency is less than 20Kbps.2. This module is just a level conversion module and does not participate in conversion analysis such as software protocols.3. When the module is connected to the computer's COM port,the computer can receive data,but it cannot communicate with your slave device as a host.The computer's com port cannot generate the 13-bit start bit in the LIN protocol,but it can be connected to a development board such as a microcontroller.Package list :1pcs RS232 to LIN Bus Module1pcs DB9 Male Screw ## Features - Pure data signal conversion. - Its data is stable. - It has a green power indicator that shows the working status. - It can monitor and maintain LIN bus device communication. - SHOP WITH CONFIDENCE: To provide you with the highest quality service, If you have any question, please feel free to contact us.We will provide after-sales service until you are satisfied. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NF4GBC6 | | Best Sellers Rank | #1,083 in Serial Adapters | | Brand | DONGKER | | Color | Green | | Compatible Devices | Monitor | | Connector Type | db9 | | Customer Reviews | 4.5 out of 5 stars 3 Reviews | | Finish | Green | | Finish Type | Green | | Input Voltage | 12 Volts | | Item Weight | 0.24 Kilograms | | Manufacturer | DONGKER | | Mfr Part Number | 1 | | Model Number | 1 | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | UPC | 770343844189 | | Unit Count | 1 Count | ## Product Details - **Brand:** DONGKER - **Color:** Green - **Compatible Devices:** Monitor - **Connector Type:** db9 - **Finish Type:** Green ## Images ![DONGKER RS232 to LIN Bus Module,RS485 to UART Converter DB9 Female Connector Breakout Board - Image 1](https://m.media-amazon.com/images/I/61kNcZi98RL.jpg) ![DONGKER RS232 to LIN Bus Module,RS485 to UART Converter DB9 Female Connector Breakout Board - Image 2](https://m.media-amazon.com/images/I/6108lb4abNL.jpg) ![DONGKER RS232 to LIN Bus Module,RS485 to UART Converter DB9 Female Connector Breakout Board - Image 3](https://m.media-amazon.com/images/I/61d4mkRyufL.jpg) ![DONGKER RS232 to LIN Bus Module,RS485 to UART Converter DB9 Female Connector Breakout Board - Image 4](https://m.media-amazon.com/images/I/61soe25cXFL.jpg) ![DONGKER RS232 to LIN Bus Module,RS485 to UART Converter DB9 Female Connector Breakout Board - Image 5](https://m.media-amazon.com/images/I/61TF61pg9IL.jpg) ## Frequently Bought Together - DONGKER RS232 to LIN Bus Module,RS485 to UART Converter DB9 Female Connector Breakout Board - OIKWAN USB to RS232, USB Serial Adapter with FTDI Chipset,USB 2.0 to Male DB9 Serial Cable for Windows 11,10, 8, 7, Vista, XP, 2000, Linux and Mac OS(6ft)… - DTECH Serial Adapter 3-Pack (DB9 F-F, M-F, M-M), Mini Size RS232 Coupler, Female to Male 9 Pin Connector, for PC Computer Data Transfer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/288803580-dongker-rs232-to-lin-bus-module-rs485-to-uart-converter](https://www.desertcart.us/products/288803580-dongker-rs232-to-lin-bus-module-rs485-to-uart-converter) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-20*
