ماژول مبدل USB به TTL با تراشه CP2102

CP2102 Introduction:
    CP2102 is developed silbab USB serial chip, small size, may not require any peripheral member can be simple as a USB-UART scheme, communication speed up to 1Mbps, the product is easy to upgrade to the USB serial port, but because of its small size, but it is also MLP package, a certain degree of technical difficulty of welding, so the owner of this compact design USB-UART module interface comprises a lead 5V, 3.3V, TXD, RXD, GND, wherein TXD, RXD directly MCU serial connection, convenient for debugging the initial product, even 3.3V system can take power from the module (less than 100mA), LED display module has been powered on and functioning.

Single Chip USB to UART Data Converters:
  - Integrated USB transceiver does not require external resistors
