It converts TTL signals (from 3V up to 5.5V) into RS232 standard communication signals, allowing you to connect your microcontroller’s UART (like in any ARM, Atmel, PIC, etc.) to your PC’s RS232 serial port (including USB-to-serial adapters like FTDI’s). This is the version without the DB9 connector, so you can solder the connector of your preference. MAX3232 RS232 Board serial communication. RS232 TTL Converter/Adapter Kit (MAX232) for AVR/PIC/ARM/GPS. True MAX232 Chip Works with GPS, Microchip PICs, AVR, ARM, Basic Stamps ... ...
This Converter is designed to be used by plug into a breadboard directly or by flier wires connect to your target board. The small RS232 Converter provides Rx/Tx pins and 2 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 (4-wire), or with DSR/DTR handshaking or with CTS/RTS handshaking (6-wire). 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 thru extension cable. This module works with Microchip PICs, Basic Stamps, Atoms, and any other microchip and microcontroller and anywhere you need TTL to communicate via RS232.
It can be used as a bootloader interface; with a support of a bootloader chip then you can program the microcontroller in-circuit program, such as PIC using the C6, C7 hardware serial port. Features: $1.56 JY-MCU Mini RS232 to TTL Converter Module Board (3~5V) - 3V-5V at FastTech. MAX3232 converter RS232/UART,for installing into COM port connector of PC motherboard. A feature of this module is the ability to work without an external power supply.
To do this, you must set the DTR and RTS lines of COM port to "logic one" state, and short SMD jumper on the bottom side of the module (module is shipped with a shorted jumper). Now MAX3232 chip have 3.6V power supply. When using this feature is recommended to disconnect the external power supply from VCC of module Attention! From the COM port is allowed only to supply the chip MAX3232, installed in the module.

Product Search. MCP230xx GPIO Expander on the Raspberry Pi. Expander Plug - Hardware. The expander plug is a small board with an I2C expander chip on it with 8 general-purpose digital I/O lines.
Each of the lines can be configured individually as input, or as open-collector output, or as regular output. The 2x6-pin connector has the 8 I/O signals, +3.3V and ground, as well as the raw PWR voltage and the IRQ line. The Breadboard Connector can be used with this plug by attaching it to pins 1..8 of the on-board connector: An I2C bus running at 3.3V is used for I/O, with all the power and signal lines brought out to to both sides of the board to allow daisy-chaining with other I2C-conformant boards. Configuration¶ There are two solder jumpers to configure each plug for one of the following 7-bit I2C addresses: Header Pinouts¶ Design Info¶ Dimensions: 21.1 x 24.1 mm (Expander Plug) and 21.1 x 11.5 (Breadboard Connector) CadSoft EAGLE design files: see below.
