RS232 Male to TTL Converter KIT 3.3V DTE 

A Male version of our RS232 To TTL level converter kit in DTE mode. This Male RS232 to TTL acts as a pc side device (Data Terminal Equipment Mode)

This is supplied in kit form for educational purposes or for those on a budget. Very popular with schools and colleges!
This is a kit form of P/N: 4402.

This module converts signals between RS232 voltage levels and TTL voltage levels in DTE mode. Fully assembled with pins on underside for direct breadboarding facility out of the box!It is bi-directional, where TTL signals are converted to RS232 levels and RS232 levels are converted to TTL levels.

RoHS compliant - professional 2-layer, red, nickel/immersion gold (PCB).

Features:

  • High speed, replaceable MAX3232 / ICL3232 based. Device fitted supports upto 230kbps.
  • Works with PCs or Laptops.
  • +3.3V or +5V signals levels at the TTL level.
  • Ultra low current power status LED
  • Has a Male RS232 9 Pin Connector with DTE mode signalling

Single 3.3V or 5V supply required via header.

Parts Supplied in Kit:

  • 1 x High quality Red PCB - Gold Plated RoHS
  • 1 x Male serial port connector
  • 1 x  MAXIM MAX3232 / Intersil ICL3232 device (Depending on Stock)
  • 1 x DIL socket
  • 5 x capacitors
  • 1 x 1k resistor (for LED)
  • 1 x ultra low current red LED (for power status)
What you will need:
  • Basic electronics knowledge e.g. observing polarity of components.
  • Soldering iron, soldering skills, 5V supply etc...


Once assembled - very handy for breadboarding!
RS232 to TTL image.

TTL Connections:

Pin 1: GND - this pin is the ground pin. This pin is usually connected to the 0V rail of the application hardware.

Pin 2: VCC(+) - this pin requires 3.3V (or 5V for 5V TTL logic) to be supplied to the board for power.

Pin 3: RX (input - from UART into PC) - this pin is usually connected to the TX output pin of the UART in the microcontroller.
This is an input pin.

Pin 4: TX (output - from PC to UART) - this pin is usually connected to the RX pin of the UART in the microcontroller.
This is an output pin and will be data from the RS232/PC side of the converter.

Pin 5: CTS (input - from UART into PC) - this pin is part of the RS232 "Hardware Flow Control" system.
Normally this signal is used by the UART to flag to the PC when the UART is ready to receive data.
However, because of the various interpretations of the RS232 "standard", the exact way this signal may be used will
change from system to system.

Pin 6: RTS (output - from the PC to the UART) - this pin is part of the RS232 "Hardware Flow Control" system.
Normally this signal is used by the PC to flag when the microcontroller can send data.
However, because of the various interpretations of the RS232 "standard", the exact way this signal may be used will
change from system to system.
