433MHz STM32WL33 Wireless SoC Module RF transceiver E04-400M20S 20dbm 3.5KM W-MBUS Small Size Low Power Stamp Hole/IPEX

E04-400M20S is a wireless communication module designed based on STMicroelectronics' newly launched STM32WL33KCV6 (ARM Cortex-M0+) SoC, which is characterised by far-reaching communication, low standby power consumption, strong anti-jamming capability, rich interface resources, strong processing capability and small form factor. It is also suitable for 433/470MHz band chip wireless module, using industrial-grade high-precision 32.768KHz and 48MHz crystals to ensure the stable operation of the module. E04-400M20S wireless communication module needs user's secondary development, which can be widely used in IOT industry.
