<p>A very small size USB to TTL serial module, the module uses Micro-USB interface, compatible with data cable, the module width and data cable plug width, directly inserted in the data line Micro-USB plug to use, very small and convenient. Compared to the use of A-type USB male connector directly plugged into the PC on the USB to TTL module, this module to connect the development board and other serial devices more convenient.</p> <p>Module based on CH340C chip, and CH340G, CH340T chip drive exactly the same. Module can be used to STC microcontroller and other support serial download program microcontroller download program, or as a PC and microcontroller serial communication line, stable and reliable.</p> <p>1) driver IC CH340 is a USB bus adapter chip, to achieve USB to serial or USB to print port. CH340 built-in transceiver buffer, support for simplex, half duplex or full duplex asynchronous serial communication. The serial data includes one low-level start bit, 5, 6, 7 or 8 data bits, one or two high-level stop bits, and supports odd parity \/ even parity \/ flag check \/ blank Test.</p> <p>CH340 support common communication baud rate: 50,75,100,110,134.5,150,300,600,900,1200,1800,2400,3600,4800,9600,14400,19200,28800,33600,38400,56000, ; \/ \u0026 gt; and \u0026 ; ID = 0.0 \u0026 gt;</p> <p>2) Development board power supply The following are the same as the \</p>
