    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    ready to use from the box, it has two separate rs232 instead of description (added in 1.78 fw). Brand device with the same functionality is 10 times more expensive

    Cons:

    Not really a cons! Ralink chip is hot enough, I preferred to use a little heatsink. Second usart is only on the board without any connector soldered.
    Only tx rx lines and rts for usart 1 (gpio1, checked only in 1.78 fw)

    OtherThoughts:

    Placed in a plastic case. added an rs485 converter (max232+max485)on the second usart, and now it is a universal gateway for access to the industrial equipment)

    Bottomline:

    if you need remote access to any device with serial port this is just exactly what you need.
