Iduino ST1125 Converter module 1 pc(s) Compatible with (development kits): Arduino

This card converts a USB connection into a 5-volt TX and RX serial connection! Connect directly to the Arduino Mini, Arduino Ethernet, or other microcontrollers to communicate with her computer. One of the great features of this card is a jumper on the back of the card, with which the card can be configured to 3.3 V or 5 V (both output power and I/O level). This board comes standard with 5V. However, you can cut off the standard track and add a solder bridge if you need to switch to 3.3V.This text is machine translated.
