The is a serial port converter module designed to bridge the gap between RS232 signals and TTL (Transistor-Transistor Logic) levels. It is built around the MAX3232 integrated circuit, which allows standard COM port signals (typically ±12Vplus or minus 12 cap V hw-044 datasheet

Depending on your setup, you may still need a DB9-to-USB adapter if your modern computer lacks a native COM port. | Pin Number | Pin Name | Description
