The μVGA-III module is a compact and cost effective standalone VGA graphics engine powered by the PICASO graphics processor. It can provide a QVGA/VGA/WVGA graphics solution to any embedded project with its powerful graphics, text, image and animation capabilities, along with countless more features built inside the module.
Depending on the programming environment selected when using 4D Systems’ Workshop 4 IDE Software, the user can choose to program the μVGA-III module as a stand-alone device, or as a slave device to an external host controller.
When the μVGA-III is used as a stand-alone device, it allows the user to take complete control of all available resources on that hardware platform such as the Serial Ports, uSD memory card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the μVGA-III module via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop practical applications.
When the μVGA-III is used as a serial slave device to an external host controller, the host sends specific commands over its serial UART to the μVGA-III to produce the desired user displays.
The μVGA-III features a remote VGA connector, which is able to be disconnected from the PCB. The remote VGA connector enables flexible mounting and connection options when using the μVGA-III.
A 30 way header is provided on the rear of the PCB, which is left unpopulated from the factory, however the header is provided with the module. This can be soldered by the user if required, to gain additional IO and comms if required. Wires can also be soldered directly to the PCB if desired.
This is an evaluation board for the Silicon Laboratories Si4703 FM tuner chip. Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.
Using this board we are able to pick up multiple stations just as well as with a standard FM radio. The board breaks out all major pins and makes it easy to incorporate this great chip into your next radio project. Also, by plugging headphones into the 3.5mm audio jack, you effectively use the cable in your headphones as an antenna! Therefore, this board does not require an external antenna if using headphones or a 3.5mm audio cable longer than 3 feet.

This is the same product as the XBee Shield with a multitude of extra parts including 2 XBee modules, the popular XBee Explorer, and headers for the shield. All these parts comes in fancy clamshell packaging meant for our distributors that need it. Regular customers are welcome to order, but we want to limit the amount of extra packaging finding its way into the trash heap.
Our entire goal for the XBee Kit was to make wireless communication simple. Connect one XBee to the shield and your Arduino, connect the other XBee to the Explorer board and your computer, and you’ll be able to seamlessly pass serial data to and from your Arduino wirelessly! Using this connection, you can transmit remote sensor data, or send data from your computer to update a scoreboard, or drive a robot from your keyboard!
The XBee Shield mates directly with an Arduino Pro or USB board, and equips it with wireless communication capabilities using the popular XBee module. This is SparkFun’s own design and is a distant relative to the official XBee Shield from Arduino.
The serial pins (DIN and DOUT) of the XBee are connected through an SPDT switch, which allows you to select a connection to either the UART pins (D0, D1) or any digital pins on the Arduino (D2 and D3 default). Power is taken from the 5V pin of the Arduino and regulated on-board to 3.3VDC before being supplied to the XBee. The shield also takes care of level shifting on the DIN pin of the XBee.
The board also includes LEDs to indicate power and activity on DIN, DOUT, RSSI, and DIO5 pins of the XBee. The Arduino’s reset button is brought out on the shield, and a 12x11 grid of 0.1" holes are available for prototyping.
