I did not think I was purchasing a bag of parts that need to be assembled with a soldering iron.The first picture shows an assembled part, which is what I expected to receive. I don't have a soldering iron, so I am out of luck.The first picture should show the disassembled parts, not the first one, so you know what you are purchasing.

I had one that used a DB9 but it was bulky and hard to custom wire. These are nice once you solder the connector on. They work great.Currently have one on a NEO-GPS chip and the other on an Arduino. Only running 9600bps but it is rock solid.

Ich weiß nicht, was los war, aber die haben bei mir nicht funktioniert.Zumindest habe ich aus einer RS232 Quelle keine TTL Signal bekommen.Vielleicht lag es an mir, aber ich musste die zurückschicken.

Used this on an Esp32 project to monitor a solar controller via modbus rs232. Need to solder the connectors on or wires directly to the board. They do not come soldered on. Works great. Will buy again if I need to make another one

Bought this for a project needing RS232 control with an RPi. The Treedix board is tiny and with soldered-on leads it is small enough to easily tuck inside a regular RPi case, just add a tiny strip of electrical tape to cover the back-end of the leads. I added a 3 pin terminal block to the case for the external plug and ran the RS232 leads to that and mapped the Logic leads to GPIO. Much better than the giant DB9 interface most adapter boards come with. I am buying an extra set just to keep in the project parts drawer.
