DSD TECH SH-U09C2 USB to TTL Adapter Built-in FTDI FT232RL IC for Debugging and Programming

Q: Why does the product photo have a jumper across txd and rxd?

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?

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?

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?

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.
