The MAX485 TTL To RS485 Module converts TTL signal to RS485 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. RoboticsBD
This converter lets you send and receive data using the RS485 network from your Arduino/microcontroller. Similar to Serial TTL and RS232 interfaces, the RS485 lets you transfer data between microcontrollers and devices but with extra features! RS485 is an industry standard protocol for data transfer and provides numerous advantages. RoboticsBD
It lets you transfer data between up to 32 devices, through the same data line over a cable length of up to 1.2km (4000ft) with a maximum data rate of 10Mbit/s. This converter is designed for office and industrial applications (non-isolated) and provides superior characteristics/features normally found only on more expensive units. RoboticsBD
