UART TLL to RS485 v2 conversion module

The UART TTL to RS485 V2 communication circuit is designed to help you transfer the communication from the UART TTL communication standard (Microcontroller, embedded computer, ...) to the RS485 communication standard and vice versa.

TTL to RS485 V2 UART communication circuit is designed with high anti-jamming ability, integrated buffers, self-healing fuse, anti-jamming Diod to make the system run more stable, safer and does not burn the control board. central control. The RS485 communication part on the circuit has Mass pin, if the system has a ground here, the ground can be used to connect to this Mass to increase the resistance to noise and lightning.

The circuit supports the connection of multiple RS485 points on the bus line, the circuit is designed so that the points can be connected "hot" without fear of the module's death without disconnecting the total line.

SPECIFICATIONS:

• Operating voltage: 3 - 5VDC.
• TTL communication voltage: 3 - 5VDC.
• RS485 transmission distance can be up to 1km (recommended to use less than 800m and dedicated bus cable for RS485).
• Standard pin 2.54mm TTL.
• There are LEDs to notify the status of RX and TX transmission.
