CP2102 USB to TTL Converter

CP2102 USB to TTL Converter This CP2102 UART module is a USB to TTL UART Converter module which is based on CP2102 Bridge by SiLabs. This CP2102 UART module is compliant with USB2.0 full-speed devices with an integrated transceiver. The USB function controller manages all data transfers between the USB and the UART as well as command requests generated by the USB host controller and commands for controlling the function of the UART. The USB Suspend and Resume signals are supported for power management of both the CP2102 device as well as external circuitry.. CP2102 USB to TTL Pin Out: Pin Name Description VCCIO Jumper Configurable VCC (3.3v or 5v) Out Pin GND Ground PWR LED Power Indicator LED TxD Asynchronous data output (UART Transmit) Tx LED UART Transmit (data out) Indicator LED RxD Asynchronous data input (UART Receive) Rx LED UART Receive (data in) Indicator LED RTS Ready to Send control output (active low) CTS Clear To Send control input (active low) GND Ground Device Reset. The open-drain output of internal POR or VDD monitor. An external source can initiate a system reset by driving this pin low for at least 15 μs. This pin is driven low when the CP2102/9 enters the USB suspend state. SUSPEND This pin is driven high when the CP2102 enters the USB suspend state RI Ring Indicator control input (active low) DCD Data Carrier Detect control input (active low) DTR Data Terminal Ready control output (active low) DSR Data Set Ready control input (active low) Package Includes: 1x CP2102 USB to TTL Converter Documents: Tutorial Datasheet Related Products: IC Programmers | Testers | Data Converters

CP2102 USB 2.0 to TTL UART Serial Converter Module 5 Pin This USB to TTL adapter is based on the CP2102 USB to TTL serial converter IC. It is commonly used when microcontrollers like Arduino, Raspberry Pi, PIC etc have to communicate with computers through serial communication. As USB has DATA lines D+ and D- that can be connected and routed by CMOS switches. The USB can be connected to many peripheral devices and has a very fast speed of data transfer also it is used with Windows, Mac or any other operating system. On the other hand, Arduino and other microcontrollers works on UART data transfer protocol i.e. TTL logic level data transfer protocol it only works on 0V or 5V logic levels. That is why we need a USB to TTL serial converter IC so that Arduino or any other controller which work on UART protocol can be connected to the computer. It can also be used to program and or communicate with a GPS/GSM module through AT commands. The module supports both 3.3V and 5V interface. Features: Stable and reliable chipset CP2102.
