USB-UART CH340 converter board

This small adapter converts USB communication into UART (serial) communication, and everything you might need is already on this small board. In addition to the classic UART pins that are arranged in the standard layout: DTR, RXD, TXD, VCC, CTS, GND, other pins available of the CH340 chip are also available on header: RS232, RI, DCD, DSR, RST and CTS.

Indication LEDs show activity on RXT and TXD lines, and a 500mA fuse protects this programmer, the USB port of the computer that is connected, and other devices connected to it from damage. Additionally, there is a voltage regulator and a switch on the board, and it is possible to choose the output voltage of 3.3V or 5V, depending on the device you are using. The logic of the UART signal is always 3.3V, but don't worry, 5V devices will work with 3V3 UART logic without any problems. Use a USB-C cable to connect.

• USB - UART bridge: CH340
• Input voltage: 5V (USB)
• Output voltage: 3.3V ili 5V, selected using the switch
• UART signal logic level: 3.3V
• USB connector: USB-C
• Power LED and RXD/TXD indication LEDs
• Dimensions: 38 x 22 mm

This is a USB to TTL serial cable, with a FTDI FT232RL usb/serial chip embedded in the head. It has a 6-pin socket at the end with 5V power and ground, as well as RX, TX, RTS and CTS at 3V logic levels, and it's 914 mm long. Because the cable is 5V-logic compliant, you can use it with 3v or 5v logic just fine - no level shifting required.
