Description: Serial Port RS485 To TTL UART Level Converter DC 3.3V 5V Module
This RS485 to TTL Converter module is based of MAX485 chip, which is one of the most relied on when working with RS485 Bus. This module supports 3.3 V and 5 V power supplies, and TTL Levels. It can connect and identify up to 128 nodes on the RS485 bus. This module also supports very long range of the bus.
This RS485 to TTL Converter Module can support up to 800 meter of bus length. It has connections for RX,TX, +ve and GND, on one side, and other side has connection for RS485 bus. It also has the Indicators for the Receive and Transmit Signals. And, the thickness of PCB is 0.8 mm, which enables it to be used as add-on on any of your PCBs or devices.
- 3.3V perfectly compatible with 5.0V power supply
- 3.3V and 5.0V signal perfectly compatible
- Working temperature range: -40°C to + 85°C
- Transmission distance up to kilometers (with 850 meters of 2 * 1.5 cable to do the test, it is recommended to use in the 800 meters, more than 800 meters, please add repeaters)
- Semi-hole process design, the thickness of 0.8mm, makes it easy to use as a combo board, it can also be welded terminal use
- Has RXD, TXD signal lights to observe send and receive status
- Easy to use
- Supports 3.3 V and 5 V supply
- Max Bus Length Supported: 800 metre
- LED indicators for RX and TX
- PCB Thickness: 0.8 mm for easy use in compact devices
- Connector Pitch: 2.54 mm
- Fully consider the 485 bus lightning protection design and anti-jamming design, long-distance transmission in the field, the module’s “earth” side access to the earth, can play a very good anti-jamming and lightning effect, 485 Bus more secure; indoor short distance transmission can not access the earth.
- The use of standard 2.54 pitch design, to facilitate your secondary development.
- With 120 ohm matching resistor, shorted R0 to enable matching resistor, long-distance transmission of the proposed short-circuit.
- Support multi-machine communication, allowing access to up to 128 devices on the bus.
- Support hot-swappable, there will not be other 485 chip hot plug signal plug dead phenomenon.
- Large area of copper, to prevent signal interference.
- Half-hole process design, thickness 0.8mm, can be easily used as a mother board, but also welding terminal use.
- With RXD, TXD signal indicator.
