TTL to rs232

Overview

TTL to rs232 module, a simple circuit for converting serial port TTL level to RS232 level. Use chip MAX3232 or ISP3232 (tssop16 package), and use 5V for power supply. Applicable occasions: microcontroller learning, electronic competitions, product development, graduation projects. MAX3232 supports two channels of uart to be converted into RS232. The shared circuit only has one channel connected. You can connect two channels if necessary. In addition, the above circuit is not isolated. If you want to make it isolated, you can add a photoelectric switch.
