I. Overview

2. Characteristics

Yuan-T2 is a miniature remote control transmitter module. It adopts high-performance RF chip and built-in harmonic suppression circuit. With ultra-small size,

• Low power consumption 35mA@12V (almost no power consumption when not transmitting)

• High power +26dBm@12V

• Micro

It has the characteristics of low power consumption, wide voltage and high stability, and is suitable for 23A battery power supply. It has been widely used in smart home/home appliance remote control.

9. About the antenna

The antenna is very important. Failure to connect the antenna or improper antenna will seriously affect the effect. There are usually three types of modules:

The diameter is 0.5mm to 5mm. When using this kind of antenna, be careful to spread the antenna as far as possible and keep it away from the metal body. The antenna will be more effective.

3. Patch antenna/spring, easy to install and long distance, the following antennas can be used:

1. Trolley antenna or single/multi-strand copper core wire, 315MHz corresponds to 23cm, 433.92MHz corresponds to 17cm long.

2. PCB antenna can easily pass FCC and other certifications and has good consistency, but it requires special design. Our company provides design services.
