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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfectly *by W***E on 20 October 2025* Excellent works as described ### ⭐⭐⭐⭐⭐ Sturdy and works *by D***N on 4 September 2020* I used it to program my ESP 32 boards, and it worked wonderfully, the box is so much more sturdy than just having another bare chip lying around and for what it does I think the price is exactly right.
