$6 OEM prop plug alternative

Though you could probably build-in to the board for $3-4, sometimes that is cost prohibited or to small parts for a DIY.
And by using FTDI pin-out standard, there will be multi-use.

Have you tried this? Cool idea.

Where is the transistor reset circuit for DTR ???

It is not a PropPlug without it!

The LC234X only have RTS, Prop software lets you select that instead of DRT in its menu,
If you need to invert the signal the fdti chip can be reprogrammed to do that.

I recommend that if anyone build a new P1 board, put dual rows of pins holes so it will be compatible with both Prop plug and LC234X.
For $14.99 on other mcu's platforms you get a full fledge debugger with energy trace and not just a uart-port,
so a don't make new buyer balk at having to spend more money that can not be used anywhere else.

With a few more handshake line choices, there is also this :

CP2102N-MINIEK

I use the USB-TTL CP2102 for ~$1.60 with my onboard transistor reset circuit (on my prop board). It even supplies 5V from the USB for my prop boards.
