Serial Port Level Conversion SP3232 TTL to RS232 Mutual Conversion Male And Female RS232 to TTL Module

Serial Port Level Conversion SP3232 TTL to RS232 Mutual Conversion Male And Female RS232 to TTL Module Description: The main purpose: 1. The TTL serial port of MCU, such as single-chip microcomputer, ARM, FPGA, Arduino, etc. communicate with RS232 level equipment 2. Mobile phone flashing, XBOX360 flashing, GPS, electronic compass, car inspection, DVD flashing, hard drive repair, set-top box upgrade (the realization of this part of the function requires the buyer to have the relevant flashing ability, the customer service staff of this store will not operate it) 3. Serial port expansion of the device 4. RS232 port communication with computer PC Instructions for use: (take the MCU as an example to explain how to connect each row of pins) TTL (UART) end: VCC: Connect to DC 3V-5.5V GND: Connect to GND TXD: connect to MCU.RX (signal flow: MCU.RX << SP3232 << RS232.TX) RXD: connect to MCU.TX (signal flow: MCU.TX >> SP3232 >> RS232.RX) CTS and RTS are not used by default. RS232 terminal: RXD: connect to RS232.TX (signal flow: RS232.TX >>SP3232 >> MCU.RX) TXD: connect to RS232.RX (signal flow: RS232.RX <
