DTECH DB9 Breakout Connector DB-9 Female RS232 Serial Adapter Solderless Module Board with Screw Terminals Block, Case, Long Bolts and Tail Pipes

I used this to make a ALDL cable for communicating with the ECM on older GM cars. This works perfectly and is easy to set up. I was able to use this along with a serial to USB adapter on windows 11 and was able to connect to the ECM.

Good item solved a problem and easy to work with and adjust for projects

I bought two different versions of these the db25 and the DS9. Both of them had work flawlessly to test equipment before I commit to a plug and solder the cables to it. This one gives you the chance to move cables around until you get the right combination and then solder the cables in the right order on the permanent plug. Bought a few more as spares because at any given moment I have two or three different projects going at the same time and with my luck when I need more they'll probably will not have them. I definitely recommend these for anybody that needs to make a quick and reusable cable or even as a permanent one. Beats soldering.

Little bulky but it did the trick and was easy to use.

Works great for Reading/Logging my AFR sensor.

Good

As described

It took care of a problem for me. Instead of having to squint, use a magnifying glass to see pins and generally sweat soldering connections on a DB9 connector, I got this. Saves a great deal of grief and frustration.
