TTL-RS232 serial communication module SP3232

Overview

product description

The TTL-RS232 module takes the SP3232EEN chip as the core and is used to achieve mutual conversion between TTL/COMS levels and RS232 levels. Wide operating voltage, compatible with 3.3V and 5V systems. There are LEDs on the TTL/CMOS data input/output terminals to indicate the data sending and receiving status.

Features

Working voltage: 3.0V ~ 5.5V
Chip power consumption: 0.3mA (no load, AMB=+25°, VCC=3.3V)
Maximum baud rate: 235Kbps (RL=3kΩ, CL=1000pF)
Interface: DB9_female, easy to use
