This article will provide a detailed introduction to several 2.4GHz wireless modules, aiming to help you better understand and utilize related devices.

The LoRa1280 is a high-performance wireless module operating in the 2.4GHz frequency band, designed specifically for long-range applications in the Internet of Things (IoT). It is developed by our company based on Semtech Corporation's high-performance radio frequency chip, the SX1280.

The LoRa1280 is a high-performance wireless module designed for long-range applications in the 2.4GHz frequency band within the Internet of Things (IoT). It is a series of products developed by our company based on Semtech Corporation's high-performance radio frequency chip, the SX1280. The LoRa1280 wireless module utilizes LoRa modulation, effectively addressing the limitation of short communication range found in typical 2.4GHz modules.

The entire series incorporates industrial-grade crystal oscillators with a precision of 10 parts per million (ppm). Combined with the high-penetration capabilities of the 2.4GHz frequency band and the LoRa modulation mode, these modules exhibit high sensitivity in reception and robust resistance to environmental interference. This enables them to perform functions such as wireless ranging, making them well-suited for applications requiring long-range 2.4GHz transmission.

The SX1280 is a wide-range, low-power wireless communication module that features highly accurate distance measurement capabilities.

RF2401

The RF2401 series wireless modules are designed for long-range, low-power, and high-sensitivity FSK wireless digital communication within the 2.4GHz ISM global license-free band. These modules utilize wireless chips designed by a top European RF company. In addition to their low cost, small size, and product stability, they boast a maximum transmission power of 10dBm, a receive current of 7mA, and a tested receive sensitivity of -115dBm, allowing for a maximum range of up to 500 meters. This significantly surpasses similar 2.4GHz wireless modules of its kind. The RF2401 series can be widely used in daily life and activities that require wireless connectivity.

RF2401PRO

The RF2401PRO 2.4GHz wireless module utilizes the nRF24L01+ device from Nordic Semiconductor, which is a highly integrated 2.4GHz ISM band wireless transceiver chip. The major advantage of the RF2401PRO wireless module is its capability for transmitting voice and images. However, this feature results in a relatively shorter transmission distance compared to other modules.
