## Questions & Answers

**Q: Why does the product photo have a jumper across txd and rxd?**
A: The jumper between TX and RX is mainly used for testing.
Short TX, RX means you will receive any data you send.
When you program or debug, you can quickly confirm if the TTL adapter is damaged.
It saves you time and quickly locates faults.

**Q: What is the maximum baud rate of this device?**
A: Build-in FTDI FT232RL Chip, max speed is to 3Mb/s . After testing, we found that data can be transmitted stably below 115200 baud rate.

**Q: Does this work with the arduino ide to upload sketches to the arduino pro mini?**
A: yes ,it work with arduino ide to upload sketches to pro mini.

**Q: I  want to confirm, 5v from the usb side is output to vcc as 5v or converted to 3.3v /1.8v by jumper and sets ttl interface level correct?**
A: Hi, I just checked this on mine with a DMM to verify.  Your assumption is correct: the jumper will alter the VCC to 5/3.3/1.8V.

### ⭐⭐⭐⭐⭐ Perfect for programming AVR microcontrollers
*by T***D on June 30, 2025*

I use mine to program breadboarded ATmega1284 microcontrollers. It works perfectly. There is a good tutorial online if you search for it. This product it very well made.

### ⭐⭐⭐⭐⭐ Worked perfectly
*by T***Y on September 27, 2025*

This device worked fine and did the job it advertised. Note that you’ll probably need to install the FDTI driver on some systems such as Windows 10/11.

### ⭐⭐⭐⭐⭐ This ONE device for everything, in a sturdy case
*by A***D on June 2, 2020*

I have a pile of assorted serial adapters sitting all over the place on my workbench, and I almost never use them. Either they're loose wires with unlabeled cables, or they're 5v when I need 3v3, or the power is unlabeled as well! Or my workspace is so chaotic that yet another bare board is just a recipe for shorting out my computer's USB port. This, however, is really the only device that I should have. It appears to be a genuine FTDI chip (0403:6001), with selectable power and logic levels. The pins are clearly labeled, and it comes with a set of Dupont wires. The whole thing is wrapped up in a plastic case that keeps it and your computer safe from the other stuff on the workbench. Lastly, LED indicators for power, RX, and TX help you to identify connection problems. I would appreciate maybe a little more shrouding around the pins and jumpers, but what I'd *really* like is if all my other serial adapters turned into these.
