RS232 to 3~5 Volt TTL Signal Converter This Converter is designed to be used by plug into a breadboard directly or by wires connect to your target board. The RS232 Converter provides RX/TX pins and two control pins for either DSR/DTR or CTS/RTS handshake signals. The handshaking options (Jumper configurable) can be configured as a null modem with no handshaking, or with DSR/DTR handshaking or with CTS/RTS handshaking. It has a standard DB9 female RS232 connector and can be connected to a standard PC COM port or any other terminal with a straight through extension cable. The 6-pin header can connect with any breadboard that requires serial I/O wiht the breadboard providing an operating voltage between 3.3 to 5 volts. This module can works with Microchip PICs, Basic Stamps, Atoms, and any other microchip/microcontroller or anywhere you need TTL communication via RS232. It can be used as a bootloader interface, with a support of a bootloader chip and the in-circuit program, such as PIC using the C6, C7 hardware serial port. It also can be used for bootloading with handshaking signal. 1. Null modem (no handshake) 1-2 and 5-6 2. CTS/RTS handshake 3-5 and 4-6 3. DTR/DSR handshake 1-3 and 2-4 * It is built with a true MAX3232 level conversion chip * RS-232 Bus-Pin ESD Protection Exceeds ±15 kV Using Human-Body Model (HBM) * Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards * Operates with 3V to 5.5V VCC Supply * Operates Up To 250 kbit/s * Two Drivers and Two Receivers * Low Supply Current . . . 300 μA Typical * Accepts 5V Logic Input With 3.3V Supply * Five capacitors enclosed noise filtering * Configurable handshaking signal for RTS/CTS and DST /DTR * High quality double sided printed circuit board with silk-screen and two mounting holes * Small and compact in size 1.25 x 1.25 inches * Directly plug in the breadboard * Set your Real Time project via RS-232 * Reads values and communicates with the PC * Turn your PC into a thermometer or voltmeter using Visual Basic or other software. * Control a motor, switch, sensors or what ever with your PC. * Microcontroller bootloader interface We also sell other electronics devices such as Microchip ICD2 Debugger/Programmer, ZIF Socket and varies kinds of IC SOIC/SOT to DIP Adapters, please check them out here. |
