Interface Module

SD Card Reading Writing Module for Arduino with the onboard 3.3V regulator. This SD Card module can make your SD application easier and simple. Through programming, you can read and write to the SD card using your Arduino. With the help of this module, it can use for SD Card more easily, such as for MP3 Player, MCU/ARM system control.

It can be easily interfaced as a peripheral to your Arduino, and other embedded boards and microcontrollers. Through programming, you can read and write to the SD card over the SPI interface. This module can handle 2GB  SD cards.

Note: Package Does NOT include a memory card.

The USB to RS485 Converter Adapter module support WIN7 XP Vista Linux Mac OS  provides an easy to use RS485 interface by means of a Virtual Com Port on the user’s system.

There are no command structures, whatever is sent to the Virtual Comm Port is automatically converted to RS485 and vice versa. The module is completely self-powered from the USB bus.

Controlling / Communicating with RS-485 devices from your PC has never been easier! This device is plug-and-play. It shows up as a serial/com port and is accessible from applications or hyper-terminal.

This converter provides half-duplex RS-485 communication. The Baud rate range is 75 bps to 115200 bps, maximum up to 6 Mbps. No need of external power supply for operation.

Applications :

• All kinds with RS485 port device parameter settings, data communication
• LED display of communication data
• Machine PLC data reading and writing
• Monitoring data read and write, and PTZ control
• Centralized control of household electrical appliances
• Access Control System card

This is the CP2102(6-pin) USB 2.0 to TTL UART serial converter module. This is a great little tool for embedded systems that require a serial connection to a computer. The board can simply attach to a USB bus and will appear as a standard COM port.

ThisCP2102 doesn’t require any external oscillator, it onboard-board voltage regulator, and it even uses a reprogrammable internal EEPROM for the device description. The full hardware UART has flow control for baud rates from 300bps to 921600bps.

This breakout also allows you to connect the TX/RX pins of your favorite microcontroller or serial application to the RX/TX pins of the breakout, creating a simple serial cable replacement.

Supported operating systems

Windows 98/Me/2000/7
MAC OS-9
MAC OS
X-Windows CE
Linux 2.40 or later

The USB TO UART TTL 5V 3.3V FT232RL Download Cable To Serial Adapter Module is a basic breakout board for the FTDI FT232RL USB to serial IC, Revision 2. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications.

The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

The pins labelled BLK and GRN correspond to the coloured wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.

This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.

This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use this type of connector.

One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.
