## Specification
---
- Frequency: 433Mhz.
- Frequency: 433Mhz
- Modulation: ASK
- Receiver Data Output: High - 1/2 Vcc, Low - 0.7v
- Transmitter Input Voltage: 3-12V (high voltage = more transmitting power)
- Receiver Input Voltage : 3.3-6V (high voltage = more receiving power)

## Usage
---
The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU
A popular arrangement for this kit is: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU

PT2262(Encoder) and PT2272(Decoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.
PT2262 (Encoder) and PT2272 (Decoder) are optional, but you can use them to avoid confusing whith multiple RF links and block interference. You can also integrate the encoding and decoding into the MCUs on both sides. Whenever there is no 315Mhz devices around, you can use it as a direct cable connection.

Excuse for the documentation, we will work on them. Before that, please consult us for any details, we are happy to find the answer for you ^^ We tried them using the guide from Sparkfun, it's compatible. The only difference is in package, of some excess GND pins.

We tried this RF Link Kit using the guide from Sparkfun and it's compatible. The only difference is package in the guide, which has some excess GND and VCC pins.

More over, we will make more RF modules ourselves with different frequency and capacity. The next one in plan is based on cc1100 Please suggest us about your need :)
