The Mini RS232 MAX3232 Level Turn to TTL Level Converter Board / Serial Port Converter Board has one purpose in daily life – to convert RS232 to TTL and vice versa (TX RX RTS and CTS). This will allow a microcontroller to communicate with a computer. This board is powered from the target application and can run at 3V to 5V! That’s right – power the board at 5V and the unit will convert RS232 to 5V TTL. Power the board at 3V and the board will convert RS232 to 3V CMOS TTL. It includes two indicator LEDs for TX and RX. Moreover, it runs from 300bps up to 120Kbps.

FEATURES

• This is a high-performance MAX232 RS232 to TTL 5V converter board
