RS232.TXD) RTS: Connect to RS232.RTS (Signal Flow: SP3232 ? RS232.RTS) CTS: Connect to RS232.CTS (Signal Flow: SP3232 ? RS232.CTS) Package Included: 1xRS232 to TTL Serial Port Module 4x20cm DuPont wires

Operating voltage: 3V-5V; with four bidirectional transient suppression diode signal voltage protection. RS232 communication chip: SP3232. DB9 Interface Type: Female. This module contains hard flow control, and the TTL side of the module RTS signal is not dangling, is set to enable bidirectional transceiver function by default. Prevent SP3232 from floating in some pins, causing chip oscillation and introducing high-frequency interference and increg power consumption, thus affecting the normal operation of the entire chip. This module contains over-voltage protection circuit to better protect your computer and equipment. RS232 female to TTL Serial Port Bidirectional Transceiver Module, for SST, STC, NXP microcontroller Download. Can also be used for other purposes, such as hard disk repair, write router firmware, GPS signal reading and other functions, but requires users to have a certain level of technology can be achieved.
