KNACRO RS232 to TTL Serial Port Module Bidirectional Transceiver Compatible with 3.3V 5V Hardware Automatic Flow Control with Over-Voltage Protection
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•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.
•This module contains over-voltage protection circuit to better protect your computer and equipment.
•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 increasing power consumption, thus affecting the normal operation of the entire chip.
•RS232 communication chip: SP3232. DB9 Interface Type: Female.
•Operating voltage: 3V-5V; with four bidirectional transient suppression diode signal voltage protection.
