Modul ini dapat dihubungkan dengan mikrokontroler seperti Arduino, NodeMCU, ESP32 dll.

Contoh penggunaan modul ini untuk komunikasi modbus seperti pada sensor PZEM-017 dll.

Spesifikasi :

- Tegangan Data : Sinyal 3.3V dan 5V

- Pitch : 2.54mm

- Jarak Transmisi Data : 800 m

- Suhu Operasi : -40C ~ +85C

- Dimensi : 42.8 x 15.22 x 0.8 mm

Highlights:

(1) Compatible with 3.3V and 5.0V power supply.

(2) Compatible with 3.3V and 5.0V signal.

(3) Absolute using imported chips; industrial design; anti-interference ability; while using more effective 485 lightning protection design can be used in the industrial field and harsh field environments; the working temperature of -40 to + 85 Degree Celsius ;transmission distance up to 1 kilometer (made with 850 meters of cable F1.5 tests recommended using in the 800 meters,when more than 800m please add repeaters).

(4) Semi-hole process design, thickness 0.8mm, can easily use as a picture board, it can also be welded terminal use.

(5) Has RXD, TXD signal indicator lights, monitor send and receive status.

Features:

(1) The module is fully considered lightning protection design,when long-distance transmission in the wild, the module "Connected to the ground" terminal is connected to the ground, can play a very good jamming and anti-lightning effect,so more secure; it can not connect with the ground when the indoor short-distance transmission.

(2) Using the standard 2.54 pitch design, easy to secondary development.

(3) Has a 120 ohm termination resistors, shorted R0 to enable the matching resistor.

(4) Support multi-machine communication, allowing access at up to 128 devices on the bus

(5) The module can be hot swapped, the signal does not appear dead phenomenon.

(6) A large area of copper to prevent signal interference.
