In stockThe Story
This compact RS232 to TTL converter module, based on the MAX3232 chip, enables seamless communication between RS232 and TTL UART devices. It operates at voltage levels from 3V to 5V and supports baud rates up to 120kbps, making it ideal for interfacing legacy serial equipment with modern microcontrollers. The module's tiny footprint (15.9 x 9.4 x 2.5mm) allows easy integration into space-constrained projects.
add_circle The Upside
- check Enables easy integration of RS232 devices with modern microcontrollers
- check Low power consumption and small footprint
- check Built-in ESD protection for reliable operation
remove_circle The Downside
- close Limited to 120kbps baud rate (not suitable for high-speed applications)
- close Requires external capacitors (0.1µF) for charge pump
- close No built-in isolation between RS232 and TTL sides
