USB to TTL CH340G upgrade serial converter module The CH340G USB to TTL converter module is a small 6-pin USB male to serial TTL converter based on the CH340 USB to Serial (UART) chip. CH340 series chips can work in 3 modes: USB to serial converter mode, USB to infrared converter mode and USB to printer interface converter mode. CH340G is a substitute for the PL2303 chip, it is specially used for STC microcontroller to download DVD / hard disk / router / GPS upgrade, compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc. It can support the slow-start reset button for all STC series of microcomputers. It can be powered by dual 3.3V and 5V supplies (directly from the 5V supply or by shorting the two pins that supply it with logic voltage) and work with 3.3v and 5V target devices. Three LED indicators show power on, receiver (RX) and transmitter (TX) status. Easily connect USB ports with microcontroller projects and supports Windows XP, Windows 7 32-bit, 64-bit, Windows 8.1, Windows 10 32- and 64-bit, Mac and Linux operating systems.
