CH340 UART Programmer

This USB–TTL converter is based on CH340G USB to Serial TTL converter chipset. The module can be used for 3.3V logic level signals, and has the option to switch from 5V to 3.3V logic level using a 2 pin shunt supplied with the module.
The module includes a small switch which allows the voltage available at the VC (Supply output) pin to be switched between 3.3 and 5V. Data pins include Tx, Rx. These digital pins are at 5V TTL levels allowing them to be directly interfaced most 5V microcontrollers.
