Ai-Thinker SI4432 wireless module is designed and developed by Ai-Thinker Technology. The module uses the latest version of Silicon Labs' highly integrated wireless ISM transceiver chip SI4432. The frequency range is 240~930MHz, with extremely high receiving sensitivity (-117dBm) and transmitting power (+20dBm), which greatly improves the penetration and transmission range, and the open and barrier-free communication distance is more than 1000 meters at +20dBm output power . Users do not need to understand the relevant knowledge of radio, and can use this module to easily develop wireless-related products with stable and reliable performance.

It can be widely used in various IoT scenarios:

•　Wireless remote control

•　Remote meter reading

•　Wireless access control
