MAX3485 3.3V RS485 to TTL Signal Mutual Conversion Module for Overvoltage protectionWith Signal Indicator (3.3V 1Pc)

Description

1, The module uses all industrial MAX3485ESA chip 2, With 485 signal overvoltage protection 3, With a signal, power LED indicator, send and receive situation panoramic view 4, With 120 ohm termination resistor strobe function, long-distance communication, can be directly shorted 5, The module will be 485 signal to the MAX485 signal can withstand the common-mode voltage of -7 to +12 V, the module can be solved as a result of the 485 signal common-mode voltage is too high, resulting in 485 burn or heat problems. 6, The module uses tantalum electrolytic capacitors to filter the power supply, the power quality better. 7,The module pin pin can be directly inserted in the hole plate 2.54 pitch for easy development 8, Our all modules have to undergo a rigorous test to ensure quality 9, The back of the module with a wiring diagram, to facilitate your use Package Included: 1xRS485 to TTL Signal Mutual Conversion Module Review: Works great! R5 Not installed for Termination - The adapter works great with an EP8266 to interface to another RS-485 device! Have run it at 115200 baud over a 100 foot cable. No issues. * Note: Does NOT come with resistor R5 installed to enable local termination. To enable local termination, one must jumper the two mounting pads for resistor R5. Product schematic in the listing shows a 0 ohm resistor in the circuit for R5. This is incorrect. Review: Works great - This review is for the single pack of the max 3485 3.3v board. There are 3 LEDs, one for power, one for tx, and one for rx. The board worked fine and the LEDs also work as expected to show bus traffic. There are empty solder pads to short if you want to enable termination. Good product.
