Ebyte E04-900M20S STM32WL33 850~930MHz 20dBm Wireless SoC Module - 3.5KM Communication Distance

Ebyte E04-900M20S STM32WL33 850~930MHz 20dBm Wireless SoC Module - 3.5KM Communication Distance

E04-900M20S wireless module is a SoC wireless communication module based on the newly launched STM32WL33 chip solution of STMicroelectronics. The wireless module has the characteristics of long communication distance, low standby power consumption, strong anti-interference ability, rich interface resources, strong processing ability, and small size. It is also suitable for 868/915MHz frequency band patch wireless modules, using industrial-grade high-precision 32.768KHz and 48MHz crystal oscillators to ensure stable operation of the module. This wireless module requires secondary development by the user and can be widely used in the Internet of Things industry.
