What is the 2.4 GHz module in the toy field?

By sdga:NiceRF Wireless Technology Co., Ltd

The toy industry has always been a very hot field. Under the implementation of China’s "13th Five-Year Plan" policy (that is, one couple can have a second child), the number of newborns will greatly increase, and the increase in newborns also represents The development of the toy industry brings huge potential.

With the continuous rapid development of the Internet, intelligence and technology have become the mainstream of toy development, and the traditional toy industry will gradually be eliminated. In the future, the toy industry will pay more and more attention to the interaction between people and toys, such as "listening" and "speaking" functions. The most important component to complete the interactive function between humans and toys is the wireless module, which can receive the information transmitted by humans and transmit it through the system's coding, and then "speak" to humans. Most of the wireless module frequency bands used in home toys use 2.4GHz, because the changed frequency band is the international ISM frequency band, and there is no need to apply for a wireless frequency band license. At the same time, the 2.4GHz frequency band has a short transmission distance and is very suitable for applications in Indoor places.


What is the 2.4 GHz module suitable for the toy field?

LoRa1280/LoRa1281 long-distance Lora spread spectrum 2.4 GHz module

2.4 GHz module LoRa1280 LoRa1281

LoRa1280/LoRa1281 is a long-distance 2.4 GHz high-performance IoT wireless transceiver module. It integrates Semtech's high-performance radio frequency chip SX1280/SX1281. The module uses LoRa modulation and has extremely high receiving sensitivity. LoRa1280 integrates the "time of flight" function, which can realize the function of wireless ranging. Working frequency range: 2400-2500MHz, LoRa modulation, data transmission rate: @LoRa=0.476-202 Kbps, maximum output power: 12.5dBm, sensitivity up to -132dBm@LoRa, data packet communication mode (transceive FiFo 256 bytes), work Voltage range: 1.8-3.7 V, working temperature range: -40~+85°C, can be used in wireless remote control, smart home, toy control, health detection and other fields.


LoRa1280F27 LoRa1281F27 500mW 2.4 GHz module

2.4 GHz module LoRa1280F27 LoRa1281F27

The LoRa1280F27/LoRa1281F27 product uses Semtech’s SX1280/SX1281 radio frequency chip, with an external PA, and the output power is 500mW (27dBm). The working frequency band is 2.4GHz. Lora modulation is adopted, which has better receiving sensitivity and anti-interference ability. At the same time, SX1280 also has built-in wireless ranging function. Operating frequency range: 2400-2500MHz, maximum output power: 27.0dBm, sensitivity up to -132dBm@LoRa, data transmission rate: @LoRa=0.476-202kbps, LoRa modulation, data packet communication mode (transceive FiFo 256 bytes), working voltage Range: 2.0-5.5V, working temperature range: -40~+85°C. It can be used in toy control, smart home, and other fields.
