Taking a break

 We're taking a break moving shop and hope to be back soon. We hope to start shipping orders in Nov 2018. 

The kit is consists of a transmitter and a receiver, popularly 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 scenario: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU.

PT2272 (Encoder) and PT2262 (Decoder) are optional, but their existence is to:

  • avoid confusing when multiple RF links are in range; and
  • isolate disturbance.

You can integrate the encoding and decoding work into the MCU functions on both sides. Whenever there are no RF devices around, you may use it with a direct cable connection.
