USB to UART TTL module CP2102

Technical Data:

• TXD: CP2102data transmit pin is usually connected to RXD other modules. TLL levelCan notbe directly connected to RS232 level .
• RXD: CP2102 sData receive pinis usually connected to TXD other modules. TLL levelCan not be directlyconnected to RS232 level .
• GND: CP2102 ground
• 5v: Output 5vpower supply ( maximum 500mA)
• DTR/RST: Burning pro mini , etc. , whenthe board provides reset timing.
• 3.3v: 3.3v power output
• with 500mA resettable fuse , short circuit can effectively ensure that theload module or modules for computer damage .
• Power / TXD / RXD LEDsList All , easier to debug.
