Description: This Function Generator Kit is based around the XR-2206 monolithic function generator IC, and can produce sine, triangle, and 5V square waves with frequencies ranging from 15Hz to over 500kHz.

A selector switch allows you to pick either a sine or triangle wave to be output to the 'WAVE' pin. The amplitude of this wave can be adjusted from about 1V up to either 7V (triangle) or 5V (sine). A square wave is also emitted by the XR-2206, and run a couple times through an inverter to even the wave out. This wave will have a maximum of 5V, so it can be interfaced with a microcontroller or other TTL-level devices.

There are two selectable frequency ranges as well. When the 'FREQ' switch is set to Low, the frequency can be adjusted from 15Hz to 4.5kHz. In the High position, the frequency can go from 3kHz to about 650kHz. Two pots are used to adjust the frequency, providing both coarse and fine adjustments. The XR-2206 can emit frequencies from 0.01Hz up to 1MHz, if you need a frequency that this kit doesn't provide, we've broken out a couple extra resistors (R8, and R9), to give you the ability to customize your kit.

The XR-2206 requires a relatively high voltage for normal operation, this kit has it running at 12V. This means you'll need at least ~14VDC (no greater than 35V though!) to get the kit running at the optimal 12V. If you just want to use the 5V square wave output though, you could probably cheat and use a 9V wall adapter; we've used this in a few tests, and it hasn't caused us any problems.

Assembly is straight-forward and can be done with a simple multimeter for testing resistor and potentiometer values. The board is labeled clearly and should be good for beginners.

Lastly, if you'd like a quick and easy display of the frequency. This kit can be mated directly with a Frequency Counter Kit!

Description: This is only the 315MHz transmitter. This will work with the RF Links at 315MHz at either baud rate. Only one 315MHz transmitter will work within the same location.

This wireless data is the easiest to use, lowest cost RF link we have ever seen! Use these components to transmit position data, temperature data, even current program register values wirelessly to the receiver. These modules have up to 500 ft range in open space. The transmitter operates from 2-12V. The higher the Voltage, the greater the range - see range test data in the documents section.

We have used these modules extensively and have been very impressed with their ease of use and direct interface to an MCU. The theory of operation is very simple. What the transmitter 'sees' on its data pin is what the receiver outputs on its data pin. If you can configure the UART module on a PIC, you have an instant wireless data connection. The typical range is 500ft for open area.

This is an ASK transmitter module with an output of up to 8mW depending on power supply voltage. The transmitter is based on SAW resonator and accepts digital inputs, can operate from 2 to 12 Volts-DC, and makes building RF enabled products very easy.

Features:

• 315  MHz Transmitter Operation
• 500 Ft. Range - Dependent on Transmitter Power Supply
• 2400 or 4800bps transfer rate
• Low cost
• Extremely small and light weight
