433MHz的RF鏈路包
資料來源：https://www.seeedstudio.com/433Mhz-RF-link-kit-p-127.html
Description
The kit is consisted of transmitter and receiver, popular used for remote control.
Basic Specification:
Frequency: 433Mhz.
Modulation: ASK
Receiver data output: High - 1/2 Vcc, Low - 0.7v
Transmitor input voltage: 3-12V (high voltage = more transmitting power)
Transmitting range (work at 5V): 40m indoor, and 100m in open air
Usage:
The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder ->MCU,
PT2272(Encoder) and PT2262(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.
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.
Moreover, 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 .

描述
該套件由發射器和接收器，流行的用於遠程控制。
基本規格：
- 頻率：433MHZ。
- 調製方式：ASK
- 接收數據輸出：高 - 1/2 Vcc時，低 - 0.7V
- Transmitor輸入電壓：3-12V（高電壓=更多的發射功率）
- 傳輸距離（在5V工作）：40米室內，和100米的露天
用法：
受歡迎的鏈接是這樣的：MCU - >編碼 - >發射器------接收器 - >解碼器 - > MCU，
PT2272（編碼器）和PT2262（解碼器）是可選的，它們的存在是：1）避免混淆當範圍2多RF鏈路）隔離干擾。可以在編碼和解碼工作集成到在兩側所述MCU。每當周圍沒有315MHZ的設備，你可以用它直接電纜連接。
藉口的文檔，我們將在他們的工作。在此之前，請諮詢我們的任何細節，我們很高興找到了答案給你。我們試圖用他們的引導，從Sparkfun，它是兼容的。唯一的區別是在包裝，一些多餘的GND引腳。
此外，我們將更加射頻模塊與自己不同的頻率和容量。在計劃下一個基於CC1100請建議我們介紹一下您的需要。
