I. Overview

•

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

transmitting)

High power +26dBm@12V

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

Model 2.4V 3V 12V Recommended

1. The DAT data terminal is 3V level and is directly connected to the encoding IC.

2. Some coding ICs (MCUs) output a 3.6-12V level. Please connect a 22K resistor (3.6-

5V) or a 51K resistor between the DAT and the coding IC.resistance (5-12V) to protect

the module.

3. A stable power supply is very important. Please filter it well and try to stay away from

large inductors. DC-DC recommends using low frequency.

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:

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

corresponds to 17cm long.

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.2. PCB antenna can

easily pass FCC and other certifications and has good consistency, but it requires special design. Our

company provides design services.

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