Great for USB to TTL interfacing.
I needed this to program a Nextron LCD display via a USB port. At first, my Nextron screen showed only lines and static. Then I realized the power jumper was set to 3 volts, and the Nextron required 5 volts. After that, no problems. It just works.

Excellent USB to Serial interface unit.
This is a well designed unit at a remarkable low price for what it does. The material quality is top rate. Very convenient item for interfacing a USB port to a serial port. I simply plug it into a USB port on my laptop and use the provided cable to connect the interface unit to the serial interface pins of my microcontroller board. The use of clear plastic to encase the unit is very smart. It allows you to view the LEDs monitoring the Rx and Tx lines to ensure data is transferring properly. Makes programming the microprocessor easy, using the software on my Windows 10 computer. Installing the Win 10 driver was also easy by downloading it from the FTDI website. It also provides the use of 3.3 volt or 5 volt logic by use of a simple jumper on the unit. They also provide a jumper for loop back testing. Highly recommend it.

Real FTDI chip. Works great.
I bought this adapter to interface a uBlox Neo-8M GPS module to use as a time reference with PPS to create a stratum 1 NTP server on Windows 10. It powers the GPS with no problem. I soldered a lead to the CD (carrier detect) hole on the PCB and connected it to the PPS output of the GPS module. It works, but be careful. It appears that the RS-232 control signals (CD, CTS, RTS, DTR, DSR, etc) are inverted. So my PPS driver was triggering on the falling edge of the CD signal instead of the leading edge. I was able to compensate for this by using an offset.

Not the cheapest but the best in function
Absolutely consistent results with this board. I really like the 3.3v / 5v selection jumper, too.

Great Product, Arrived Damaged
This is a wonderful product which functions well — however the plastic case arrived cracked which was disappointing.

Excellent choice for a genuine FTDI TTL to USB interface
I can't tell you how many of these I have bought through the years. I'm just glad they are consistently available.If you need a TTL to USB interface using a genuine FTDI chip, this is an excellent choice.BT Recommended

Extremely useful tool for ESP32 Boards without USB Ports
I bought two of these for ESP32 Cam Boards that do not have a USB Port. It connects with the included 8 Pin Female To Female ribbon cable. There are two jumpers included. One selects either 3.3 Volts or 5 Volts for power, and the other is a jumper cable that connects RX and TX to test the adapter.I am very happy with my purchase and use them quite often.
