[IC]:SI4432

[Frequency]:425~525MHz

[Power]:20dBm

[Distance]:1.6km

[Interface]:SPI

[Introduction]:E27-4333M20S is a 100mW wireless transceiver module, operates at 433MHz,with small-size(1.27 Pin pitch).E27-4333M20S is based on the original imported RF chip Si4432 from Silicon Labs. With diversified built-in antenna and excellent anti-interface performance, the chip supports frequency hopping.
