The MAX485 TTL to RS485 Module enables reliable long-distance, high-speed serial communication by converting TTL signals to the RS485 standard. Designed for stable data transfer in noisy industrial environments, it supports multi-drop networking with up to 32 devices over a single bus – reaching distances up to 1.2 km with data rates up to 10 Mbps.

Ideal for Arduino, microcontrollers, and industrial automation projects, this module features low-power operation, stable differential signaling, and easy wiring through its onboard terminal block.
