Product Information

RS232 to TTL Converter (Student/School) Kit

Serial port / PC interfacing kit for robotics and
microcontroller based projects. 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: 4202.

This module kit once assembled converts signals between RS232 voltage levels and TTL voltage levels.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, nickel/immersion gold (PCB).
Optional circuit option on PCB for PSU and TX/RX status LEDs.

Features:
  • High speed, replaceable MAX232 based. Device fitted supports upto 120kbps.
  • Works with PCs or Laptops.
  • Supports 5-wire interface i.e. handshaking (RTS/CTS) signals also
  • +5V signal levels at the TTL level.
  • Ultra low current power status LED
  • Suitable for interface to Microchip PIC, Atmel AVR and other such micros.
  • Single 5V supply required via header.

Parts Supplied in Kit:
  • 1 x High quality PCB
  • 1 x female serial port connector
  • 1 x MAX232
  • 1 x DIL socket (for MAX232 device)
  • 5 x 1uF capacitor
  • 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!

TTL Connections (5V):

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 5V 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.
