AJMRTC 5Pcs MAX3232 RS232 to TTL Serial Converter Module, MAX232CSE UART Breakout Board, Bidirectional Level Converter for MCU Serial Debugging, Industrial Communication

AJMRTC MAX3232 serial conversion breakout module adopts MAX3232 chip to achieve bidirectional conversion between RS232 and TTL UART signals. It meets TIA/EIA-232-F standard and supports 3.3V to 5.5V single power supply. Integrated ±15kV ESD protection on RS232 pins effectively prevents static damage during serial communication. TX and RX LEDs show real-time data transmission status for quick troubleshooting. It has two independent drivers and receivers, supporting baud rates from 300bps up to 250kbps. The pin header is pre-soldered for convenient prototype wiring. It works with Arduino, STM32, Raspberry Pi and various industrial serial devices. This 5-piece kit is suitable for mass serial debugging, sensor data acquisition and embedded development.
