DollaTek 2pcs TTL to RS485 Serial Port Converter Module UART Level Mutual Conversio Automatic Hardware Flow Control with Cable for Arduino
- RS485TTL: This module converts between TTL signal and RS485 signal without the need to control "Receive - Transmit". Easy operation via the serial port, compatible with 3.3V and 5.0V power supply as well as signal.
- Includes RXD and TXD signal indicators to monitor the transmit and receive status.
- With high anti-interference ability and effective 485 lead design for use in industrial and harsh environments. Transmission range of up to 1000 meters with 2 x 1.5 cables, recommended for use within 800 meters. For distances over 800 meters, the use of a repeater is recommended.
- Easy operation with 485 bus lightning protection design and anti-jamming design for safe remote transmission in the field. 485 bus safer thanks to ground side access for anti-jamming and lightning protection effect. No ground access required for indoor short distance transmission.
- Standard 2.54 pitch design for easy secondary development. With 120 ohm matching resistance and possibility of short circuit recommended for remote transmission.

One week domestic shipping. Global delivery to the US in 2 weeks.
Wide supply voltage (3.0V~30V), limit voltage 33V, recommended for use within 30V, the minimum voltage must be more than 2.8V.
Compatible with 3.3V and 5.0V signals, both can match the module.
Excellent EMC and EMI performance.
Strong anti-jamming ability and strong lightning protection design 485, the working temperature is -40-85 ℃
With end piece and silicone wire, it is very convenient to use.
With RXD and TXD signal indicators.
This module fully considers the design of lightning protection and the anti-interference design of the bus 485. It has a very high EMC (electromagnetic compatibility) and EMI (electromagnetic interference). When the remote transmission is done in the field, the connection of the "" grounding" end of the module with the earth can play an excellent anti-interference and lightning protection function, making the bus 485 safer; internal transmission at short distance cannot access the earth.
With the standard arrangement of the needle with a distance of 2.54, it is convenient for your secondary development.
With an adjustment resistance of 120 euros, R0 can briefly allow the adjustment resistance, and the short R0 is recommended for transmission over long distances.
Supports communication with multiple machines.
Package includes:
1 x TTL to R485 Converter Module
