Work perfectly in my project
Very small and neat, do exactly what they're meant to do. Interfaced my PV/Battery/Inverter unit with ESP32 perfectly.

Kinda works
Pros: Cheap, kinda worksCons: Pads break off the board very easily, the RS232 output isn't really to spec, but it's good enough that most devices will accept it.Take note of the writing "RS232<->TTL" on the board. This tells you which pads are for which interfaceTo hook up to an Arduino like device...Serial2.begin(9600, SERIAL_8N1, myRxPin, myTxPin);Converter -> Microcontroller:" + " connects to "3V3" or "5V"" - " to "GND"TTL "<-" (pointing toward board centre) to TX pinTTL "->" (pointing toward board edge) to RX pixConverter -> RS232 deviceRS232 "->" (toward board centre) to RS232 RX (D-sub pin 2)RS232 "<-" (toward board edge) to RS232 TX (D-sub pin 3)The top and bottom arrow pads are separate on either side of the board. You can hook up RTS/CTS signals on the other side.Do not connect any of the + or - pads to the RS232 side. The 4 pads for each are fully connected.
