RS232 to TTL Serial Adapter

Part Number PRORS-003232 Category

This board is usefull to connect your PC to any digital board that uses a serial port with 3.3V or 5V level. Using a MAX3232C transceiver, this serial adapter can operate with 3,3V and 5V digital signals (it also accepts 5V logic inputs with 3,3V supply). It meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial port connector mounted on PCs.


This device operates at data signaling rates up to 250kbit/s, and it has a 15kV ESD protection. Besides TX and RX signals, CTS and RTS are also available for handshaking procedures. The board is furnished with 3 different types of connectors; this gives you the possibility to interface your PC with different kinds of peripherals.


  • 3-5.5V operating voltage
  • 0.3-1mA operating curent
  • TIA/EIA-232-F serial standard
