Main chip: MAX3232; Operating voltage: 3.3V-5V; Interface: TX, RX, GND, VCC; Bauds: 300 to 115200.
Supports 3V to 5.5V power supply and provides bidirectional data communication at baud rates up to 115.2 Kbps.
This converter can be connected to an Arduino Serial pin (0,1) to convert standard Arduino TTL to RS232. It allows Arduino talk to hundreds of RS232 devices.
This converter uses MAX3232-based level shifter for converting TTL (Transistor-Transistor Logic) -level serial to standard RS232 serial.
Application: RS232 is widely used in radio modifications,phone flash, XBOX360 flash, GPS, vehicle detection, DVD flash, hard disk repair set-top box upgrade. It can be used to program STC MCU, NXP MCU, Renesas MCU, STM32 MCU, N+-2EC MCU.
