ProductDescription :

Instructions for use:

(Taking the access MCU as an example, how to connect each row of pins)

TTL (UART) side:

VCC: 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, RTS is not used by default.

RS232 side:

RXD: Connect RS232.TX (Signal Flow: RS232.TX →SP3232 → MCU.RX)

TXD: Connect to RS232.RX (Signal Flow: RS232.RX ←SP3232 ← MCU.TX)

GND: Connect to RS232.GND

CTS, RTS is not used by default.

Package Included:

3 pcs TTL to RS232 Module
