RS232 / TTL Converter MAX3232 Breakout Board

This module connects an Arduino or Raspberry Pi to a device with a serial RS232 interface. The chip converts the TTL signal of the microcontroller to RS232 levels and back. The RS232 side has a 9-pin D-Sub socket, the TTL side a 4-pin header.

Recommended alternative in a smaller design without D-Sub socket: Mini RS232 / TTL Converter MAX3232

Recommended Accessories:

• Dupont Cable M-F 20cm 20 Pieces
