Unlock Robust RS485 Connectivity
The DSD TECH SH-U12 RS485 to TTL 5V board provides a reliable interface for connecting microcontrollers like Raspberry Pi and Arduino to RS485 networks. It uses the high-stability MAX13487 chip from Maxim, ensuring robust performance for your projects. This board is designed for ease of use with clear pinouts for RS485 (A+, B-, GND) and 5V TTL (GND, RXD, TXD, 5V0).
Engineered for demanding applications, the SH-U12 includes 15KV ESD protection and TVS overvoltage protection to safeguard your sensitive electronics. It boasts a high transmission rate of up to 500Kbps and supports multi-machine communication, allowing you to connect up to 128 slave devices. LED indicators for TXD, RXD, and Power provide visual feedback on the board's status.
This module is an excellent choice for expanding your microcontroller's communication capabilities, offering a stable and high-speed solution for industrial automation, data acquisition, and networking projects. All customs duties and GST are included in the price, with ExpressBox tracked delivery to your Indian pincode.
Reliable MAX13487 Chip
The SH-U12 utilizes the MAX13487 chip from Maxim, renowned for its high stability and performance in serial communication. This ensures dependable data transfer, crucial for critical embedded systems and industrial applications where consistent connectivity is paramount. This imported module offers a quality alternative to local options.
Who It's For vs. Who Should Skip
Ideal for hobbyists, engineers, and students working with Raspberry Pi, Arduino, or other MCUs who need to establish RS485 communication. It's perfect for projects involving industrial automation, data logging, or multi-device networking. Skip if you require a 3.3V TTL interface, as this board operates on 5V TTL.
