## Description

DollaTek trademark Reg.NO:013726393Description:MAX485 chip is a low power consumption for RS-485 communication, limit the slew rate transceiver Then 5.08 (mm) pitch 2P terminal, convenient RS-485 communication wiring Chip leads all pins can be controlled through the microcontroller Operating voltage: 5V Size: 44 (mm) x14 (mm) Package Includes 5 x TTL to RS485 Module

Review: Works fine - Works fine, standard max485. Has 120 ohm termination already.
Review: Its not the journey or the end result. You need both to appreciate life. - Well designed compact pcb and very good components and soldering. No deterioration or corrosion so well stored and transported. Performs equally well although the device which needed to be connected evades communication, ive checked thoroughly and its not due to this module (reviewed item) which is doing everything it should. I may have some problems with the selection of the data direction as one rs485 is only half duplex and im hoping to correct this using txdr output on a ft232 (gpio) pin later on. Many thanks for a excellent product.

### ⭐⭐⭐⭐⭐ Works fine
*by A***R on 7 November 2025*

Works fine, standard max485. Has 120 ohm termination already.

### ⭐⭐⭐⭐⭐ Its not the journey or the end result. You need both to appreciate life.
*by C***R on 10 January 2019*

Well designed compact pcb and very good components and soldering. No deterioration or corrosion so well stored and transported. Performs equally well although the device which needed to be connected evades communication, ive checked thoroughly and its not due to this module (reviewed item) which is doing everything it should. I may have some problems with the selection of the data direction as one rs485 is only half duplex and im hoping to correct this using txdr output on a ft232 (gpio) pin later on. Many thanks for a excellent product.

### ⭐⭐⭐⭐ The enables for Rx and Tx can be tied together
*by R***B on 20 May 2023*

I had to check the Max485 specs, to find what levels enabled each half of the chip. RO enable is active LOW and DI enable is active HIGH. This means that you tie them together and just have a single logic level to switch between TX and Rx. Not sure why there is pullups on the enables which would put it into Master Tx , rather than Slave Rx when used to sniff traffic on a EPEVER Solar controller modbus. Using like this the terminator resistor 120R (R7) must be removed so signal is not double terminated. I now need to find out why there is bad checksums now and again on a very short lead (1 metre) and whether its the EPEVER controller or the Poor Solar Guardian PC application or even the serial application used to monitor. Far too flippin long, luckily I had 2 dev boards to mount it , but worked instantly through a TTL isolated USB <> Serial DSD Tech dongle which also supplied the 5V
