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