This module interfaces an Arduino or similar microcomputer to RS-485. RS485 is used for Serial Communications over longer distances than direct RS232 or TTL, and supports multiple units on the same bus (Multi-Drop). Specification: On-board MAX485 chip, is a tool for RS-485 communications, low-power, Slew-Rate Transceiver onboard then 5.08 (mm) pitch 2P terminal for easy Read more about TTL to RS485 Module MAX485 for Ardunio[…]
