This converter uses MAX202-based level shifter for converting TTL (Transistor-Transistor Logic) -level serial to standard RS232 serial.    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.  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.

Features:

1. Converts RS232 signals to TTL (0-5V) and vice versa.
2. Compatible with Arduino and other microcontrollers.
3. LED indicators for TX and RX signals.

Package Includes:

1 x DFRobot MAX202 RS232 to TTL Converter For Arduino
