AITRIP 4pcs 3.3V 5V FT232RL FTDI Mini USB to TTL Serial Converter Adapter Module for Arduino Mini Port

I received four of these the other day and plugged one in to meet an immediate testing need. Not too much to say - came right up on my WIndows-10 Pro laptop with no need to add a driver My immediate need was testing an application running on a Xiao processor. I'm using the RS-232 converter board as an RS-232 to 3V3 receiver. Driving the board with PuTTY on the PC side. Ignore the tape over the LED... It's bright! I might also wrap the board in heat-shrink to protect it from accidental shorts. Four boards should be a lifetime supply. Happy camper...

I bought these to reprogram HC-06 to RN-42. I only tested one, but I had no problem getting the board detected, the drivers installed and my BT modules flashed successfully every time. I would buy again, but these will last me a lifetime.

I didn't pay attention to the fact that it uses the mini-usb not even the micro. Needed to dig through the cables to find those since I've not used them in over 10 years.

The board is made reasonably well and is easy to use. Be sure to adjust the jumper on the FTDI board for 3.3v or 5V - it's labeled on the board so easily changed. Mine came set for 5V. I used this FDTI serial convertor to program the Pro Mini ATMEGA ATMEGA328P which does not have USB on board. I am providing the connections I used in case they are useful to others. Here are the connections for the FDTI to Pro Mini: 1. VCC (Pro Mini) to the **VCC (FTDI)**. Ensure the voltage matches your Pro Mini version (3.3V or 5V). 2. GND (Pro Mini) to the **GND (FTDI)**. 3. RXI (Pro Mini) to the **TX (FTDI)**. The RX pin on the Pro Mini receives data from the TX pin on the FTDI adapter. 4. TXO (Pro Mini) to the **RX (FTDI)**. The TX pin on the Pro Mini transmits data to the RX pin on the FTDI adapter. 5. DTR (Pro Mini) to the **DTR (FTDI)** (if available). This allows the Arduino IDE to automatically reset the Pro Mini during code upload. Note: The FDTI had a CI pin which was not essential for my purposes - I ignored it and did not connect. The product was easy to use and worked as expected! Bonus 60 Dupont jumper cables are a bonus for the price! The only thing I regret was accidently purchasing the USB Mini version instead of the USB C version. But that was my mistake so I did not ding any stars.

This is a really good value kit for building whatever TTL serial interface you want. I plugged them into a Windows 11 computer and Windows loaded the FTDI driver with no issue. There's plenty of pin header wires to make whatever cable connection you might want as well. You imagination is the limit here when it comes to what you make with the interface. The only thing I wish it had was a second USB cable. I am going to make ham radio computer control (CAT) cables with these and those will need the USB cable left in all the time, so a second one to go with the second board would have been nice.

I forgot what I was going to use these for, but I will find something. The Dupont connectors it comes with makes it worth the price alone.

This product does NOT ship with the jumper wires or the usb adapter shown in the images. if you only need the FTDI modules, it's fine. But if you don't have an adapter or jumper wires, this product is basically false advertising.

These work great, are easy to connect and easy to code for. I am reading a group of soil moisture sensors and these make the connection very easy. Very pleased.
