  • Need RS485 ? Get it !

    posted by Silly1

    Cheap, can't make anything like this myself and get anywhere close to this price.Received it within 2 weeks.It just works.The old link didn't work.Reported it and the next working day it was updated and it works.Now all you need to use it is available from this site.
    It's great and it works.Read the datasheets, they are available in English and Chinese in the link on the product page.Find out about the enable connections (especially they need to be controlled both at the same time).Not an issue but you need to know it.Support responded quick and accurate to my report of the non functioning link.
    If you need RS 485 in your Arduino or any other controller project, get this.
  • Good if you want do use a Uart protocol in your project

    - It Realy works good- You can use the 3 or 5 volts pin- The uart transmission is stable and quick- The pins are strong, i've atatched a flat cable with another module witch have around 1quilogram of weight into te pins, and it does not broke yet
    I tested this module with hyperterminal, arduino serial module, usb module, and used windows xp and win7 in pc.
    I recommend this product, It does not have any problem, and works good!
  • works for intended purpose

    On Linux works out of the box, as /dev/ttyUSBx - (x is number of particular device). Provides 3.3 and 5V. Has LED for power and transmit.
    I bought this for pic18f45XXX debugging purposes. Only tested it on arduino and it works like it should.
    Simple usb to ttl(5 and 3.3V) serial interface. If you are hobby-home-device-hacker this is must have. It is cheap and works! No need for max3232 or max323. Newer pc doesn't have serial interface this is perfect solutin.
  • Nice converter

    Very good assembly quality, shipped in anti-static packet. Has the pins for the jumper wires. Very low price, in Russia I was needed to disassemble phone cable that costs like 4 adapters.
    I'm planning to make a flasher cable to my Samsung E200 phone using this adapter ;). Ubuntu recognizes that adapter as /dev/ttyUSB0.
    Good solution for DIY projects that needs COM port ah high speed (such as programmers, flashers, etc.), also useful if computer doesn't has a COM port.
  • Excellent RS232/TTL converter, does what it says on the tin

    Simple, easy to connect, and works exactly as expected.Mounting holes in the PCB make it easy to mount in an enclosure.I connected the inputs and outputs to an oscilloscope, and the MAX3232 produces sharp, clean, well-defined signals on both the RS232 and TTL sides.The TTL output voltage matches Vcc (that is, set Vcc to 3.3V and the TTL output signal range will be 0-3.3V. Set it to 5V and it will be 0-5V.). This makes it easy to match the output voltage to your TTL circuits.The RS232 output voltages range between -5/+5V regardless of Vcc voltage (the chip has built-in charge pumps to increase the voltage for the RS232 transmitters). In compliance with the RS232 standard, it can tolerate RS232 input voltages of -25/+25 volts.While most people would just use the pins marked TX/RX to connect one RS232 device to one TTL device, the MAX3232 supports a second bi-directional channel.
    The board is contains a MAX3232 RS232-to-TTL converter and the necessary capacitors, a few LEDs to indicate when the chip is sending data, a female DE9 connector to connect to your RS232 device, and a 4x2 pin header to connect to your TTL device. Simple and handy.The primary bi-directional channel is connected to pins 2 (RX) and 3 (TX) on the DE9 connector (RS232) and to the TX and RX pins on the board, respectively. Be sure you connect the pins correctly: connect the TX pin on the MAX3232 board to your TTL device's RX pin, and the RX pin on the MAX3232 board to your TTL device's TX pin. Connect Vcc and GND to your TTL device.The second bi-directional channel is not connected to the DE9 connector and is only accessible on the pin headers. Connect your RS232 device's RX and TX pins to R2O ("RS232 out, channel 2") and R2I ("RS232 in, channel 2"), respectively. Connect your TTL device's RX and TX pins to T2O ("TTL out, channel 2") and T2I ("TTL in, c
    This board saves makes it easy to connect an RS232 device to a TTL circuit using a MAX3232 chip. I highly recommend it.The MAX3232 in this board functions the same as the very common MAX232 chip which only runs on 5.0V; the difference is that the MAX3232 runs on 3.0-5.5V input which makes it great for 3.3V TTL circuits.
