Product Name: NEW ICSH033A CP2102 multifunction Serial Module 3.3V and 5V input voltage More Items In Our Store,Click Here! SKU: 5256 Parsts No. : Package: Brand: Quantity: 1 CP2102 multifunction Serial Module 1.Introduction This item uses the USB to serial chip CP2102, it has the advantages of high-speed, stability, small size. It can help us realize the equal energy level interconversion of the USB/TTL/RS232/RS485. It is the essential tool in communication debugging. 2.Features and functions 1).Small size: the PCB board size is just 3.1CM*1.8CM, it is even smaller than the U disk. 2). Compatible with the 3.3V and 5v 3). 3.3V and 5V input voltage: can use this module to provide power suppler for the Microcontroller , the max output current is 500ma. 4). Over current protection: on-board recovery fuse, it can protect the Microcontroller and the PC from the damage of the Short Circuit. The fuse will automatic shutdown and will be work normally after the recovery of the circuit. 5).Indicator LED: When begin data transmission, the indicator LED will light. 6).TTL electronic level interface. 7).232 electronic level interface. 8).485 level interface: Automatic transceiver control no need for the control line. Default receiving state, when sending data, the state will be changed into sending state. 9).USB, TTL, RS232,,RS485 four electronic levels free transfer: unique circuit design, uses the switch to realize the functions conversion, it is very fast and convenient. 10). Stable communication rate: The max rate is 1Mbps. 11).DTR,RTS control signals: Multifunciton, support MSP430 BSL download. 3. Function 4.Interface usage: Mode Pin Function TTL Level Interface TXD TTL Transmit RXD TTL Receive GND TTL ground 232 Level Interface 232-TX 232 Transmit 232-RX 232 Receive GND 232 Ground 485 Level Interface A 485A+ B 285B- +5V Voltage Output +5V +5V Voltage Output 3.3 Voltage Output 3V3 3.3V Voltage Output DTR Output DTR Special Function RTS Output RTS Special 5.Product testing Using the USB TO TTL self-closed loop and the the USB TO RS232 self-closed loop to test the product functions. USB TO TTL self-closed loop:Use the Doupont line to connect the TTL-TXD and TTL-RXD of this module, place the dial switch according to the function introduction, then insert this module into the computer, uses the serial debugging helper to send the data, check whether there has corresponding back data. If it can receiving the receiving data, it proves that this module can work normally. USB TO RS232 self-closed loop: Use the Doupont line to connect the 232-TXD and 232-RXD of this module, place the dial switch according to the function introduction, then insert this module into the computer, uses the serial debugging helper to send the data, check whether there has corresponding back data. If it can receiving the receiving data, it proves that this module can work normally. The default state of the black two dial switch is “ON”, we have test this state, and it is suitable for all conditions. 6.Mechanical drawing Any problem, please contact us freely 1) We accept PayPal payment ONLY. inkFrog Analytics On Mar-21-14 at 01:59:11 PDT, seller added the following information:
