MAX3232 Mini RS232 to TTL Serial Converter Module for Arduino

The MAX3232 Mini RS232 to TTL Serial Converter Module is a compact, ultra-small PCB that converts RS232 serial signals to TTL logic levels and vice versa. Based on the MAX3232 IC, it enables reliable communication between microcontrollers and RS232 devices such as PCs, PLCs, and industrial equipment.

• IC: MAX3232 / FSC+0NL
• Interface: RS232 (DB9) to TTL (3.3V / 5V)
• Operating Voltage: 3.3V – 5V
• Baud Rate: Up to 250 kbps
• Ultra-compact PCB design — ideal for space-constrained projects
• Onboard capacitors — no external components required
• Compatible with Arduino, Raspberry Pi, ESP32, STM32, and other microcontrollers
• Labeled TX/RX and direction arrows for easy wiring

Perfect for serial communication projects, GPS module interfacing, industrial device communication, and any RS232-to-TTL level conversion application.
