Philippines

Highlights:
- compatible with 3.3v and 5.0v power supply.
- compatible with 3.3v and 5.0v signal.
- 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 environment; the working temperature of - 40 to
+ 85 degree celsius; transmission distance up to 1 kilometer (made with 850
Meters of cable f1.5 tests recommend using in the 800 meters when more than
800m please add repeaters).
- semi-hole process design, thickness 0.8mm, can easily use as a picture
Board, it can also be welded terminal use.
- has rxd, txd signal indicator lights, monitor send and receive status.

Features:
- the module is fully covered 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
The indoor short-distance transmission.
Using the standard 2.54 pitch design easy to secondary development.
Has a 120 ohm termination resistors, shorted r0 to enable the matching
Resistors.
- support multi-machine communication, allowing access at up to 128 devices on
The bus
The module can be hot swapped, the signal does not appear dead phenomenon.
- a large area of copper to prevent signal interference.
