RS485 to TTL Module

RS485 to TTL Module is for long range, high data rate error prone differential communication. Digital communications networks implementing the EIA-485 standard can be used effectively over long distances and in electrically noisy environments. Multiple receivers may be connected to such a network in a linear, multi-drop configuration. These characteristics make such networks useful in industrial environments and similar applications. The RS485 to TTL Module has an on Board MAX 485 Chip (it's a low power transceiver for RS485 communication) and 2P, 5.08mm connector for wires. All the pins of the chip are brough out and can be controlled by MCU. The board runs at 5V and is only 44x14mm.
