Product Description
1, the absolute use PL2303 chip, XP, Vista, Win7 under can be used. 2, with overcurrent protection, not afraid to burn the computer USB port. 3, with a 3.3V regulator chip can output 3.3V power supply voltage to the peripheral, current can reach 500ma. (Hint: Most so-called 3.3V regulated output is actually quoted from PL2303 chip, the output current is very small, can not use shop is specialized external voltage regulator chip.) 4, with 5V voltage output, can provide power to 5V peripherals. 5V voltage is taken from the USB port, the maximum current 500ma. 5, with power indicator light, TXD signal indicator, RXD signal lights, 3 large lights never Shengliao. 6, the design uses four filter capacitors for power USB port filtering to ensure the stability of the output voltage, but also to ensure the stability of the module is working. 7, module output 5-pin interface, namely: a, 5V output terminal b, 3.3V output terminal c, GND, the negative power supply d, RXD, serial data receiving end e, TXD, serial data transmission side 8, can give STC STC microcontroller 3.3V or 5V microcontroller supply and download the program directly, with this USB to serial module, you have the equivalent of a full range of chip STC microcontroller Downloader. 9, the modules are shipped with a transparent plastic cover, to avoid hand contact with circuit boards. Solve circuit board easily contact oxidation or short circuit problem caused by sweat stain, improve life.......
