[Product size]:20*14mm

[Introduction]:E04-400M20S is a SoC wireless communication module based on STMicroelectronics' newly launched STM32WL33 chip solution. 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 433/470 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.
