Designed for easy integration with microcontrollers like Arduino and Raspberry Pi, these modules support multi-device networks with built-in protections for thermal shutdown and fail-safe operation, making them ideal for industrial and IoT communication applications. ## Description Package includes: 12 x MAX485 TTL to RS-485 interface module Review: They just work - This was the second try for this type of equipment. First one (3.3V, auto direction) did nor work. These worked like a champ. Review: Works, but may have to remove R7? - After multiple failed attempts to get 2 of these boards communicating with each other, I found something that mentioned a "terminating resistor" (R7) that should only be present on the last device in your RS485 run. I removed R7 on two boards and they successfully exchanged messages with each other. I have not yet tested more than 2 devices communicating on the same bus. I'm not sure yet if it will work if none of them have R7 installed. Also, if you are attempting to use these with arduino and the software serial library, this might be a helpful hint: pay attention to which pins have interrupt capability. You must receive serial data using an interrupt enabled input pin. The boards themselves seem reasonably well made. Solder joints all look good. ## Features - MAX485 chip is a low power consumption for RS-485 communication, draw between 120ĀµA and 500ĀµA of, limit the slew rate transceiver to allow serial communication over very long cable runs (up 4000 feet / 1200 meters). The 5.08 (mm) pitch 2P terminal, convenient RS-485 communication wiring.Chip leads all pins can be controlled through the microcontroller. - RS485 transceiver module Serial data can be transmitted in both directions (half duplex) at a data rate up to 2.5Mbps. It is possible to connect multiple modules together for communication between 2 or more devicesļ¼ˆup to 32ļ¼‰. For even greater distances two modules can be configured as a repeater. - RS-485 module applicable to Low-Power RS-485 Transceivers, Low-Power RS-422 Transceivers, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks. - Supply current when unloaded or fully loaded with disabled drivers. Data connections to the modules are provided by a standard 0.1"""" pitch header pins which can also be soldered into standard prototyping PCB and breadboards. Screw terminals provide convention connection to the actual data cable. - Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B094MKRTRC | | Brand | DORHEA | | Color | blue | | Colour | blue | | Compatible Devices | PC, Laptops | | Compatible devices | PC, Laptops | | Connector Type | Serial Adapter | | Connector type | Serial Adapter | | Customer Reviews | 4.0 out of 5 stars 43 Reviews | | Input Voltage | 5 Volts | | Item Weight | 0.06 Kilograms | | Item weight | 0.06 Kilograms | | Manufacturer | DORHEA | | Mfr Part Number | 14667-1 | | Number of Items | 12 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | Laptop | | Specific uses for product | Laptop | | UPC | 701715471146 | | Unit Count | 12.0 Count | | Warranty Type | Limited | ## Product Details - **Brand:** DORHEA - **Colour:** blue - **Compatible devices:** PC, Laptops - **Connector type:** Serial Adapter - **Specific uses for product:** Laptop ## Images ![12Pcs MAX485 RS485 Transceiver Module TTL UART Serial to RS485 Instrument Interface Module Max458 Chip RS-485 Communication Transceiver 5V SCM Development Accessories Board for Ardu ino Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/81bori5F+MS.jpg) ![12Pcs MAX485 RS485 Transceiver Module TTL UART Serial to RS485 Instrument Interface Module Max458 Chip RS-485 Communication Transceiver 5V SCM Development Accessories Board for Ardu ino Raspberry Pi - Image 2](https://m.media-amazon.com/images/I/51EBvE-sXxS.jpg) ![12Pcs MAX485 RS485 Transceiver Module TTL UART Serial to RS485 Instrument Interface Module Max458 Chip RS-485 Communication Transceiver 5V SCM Development Accessories Board for Ardu ino Raspberry Pi - Image 3](https://m.media-amazon.com/images/I/61OGWawIZ3S.jpg) ![12Pcs MAX485 RS485 Transceiver Module TTL UART Serial to RS485 Instrument Interface Module Max458 Chip RS-485 Communication Transceiver 5V SCM Development Accessories Board for Ardu ino Raspberry Pi - Image 4](https://m.media-amazon.com/images/I/512WQECIIYS.jpg) ![12Pcs MAX485 RS485 Transceiver Module TTL UART Serial to RS485 Instrument Interface Module Max458 Chip RS-485 Communication Transceiver 5V SCM Development Accessories Board for Ardu ino Raspberry Pi - Image 5](https://m.media-amazon.com/images/I/418OJ4HxuoS.jpg) ## Customer Reviews ### ā­ā­ā­ā­ā­ They just work *by B***E on 22 March 2026* This was the second try for this type of equipment.
