[Introduction]:The E22P-915M30S series modules are surface-mount LoRa™ wireless modules developed independently based on Semtech's high-performance SX1262 RF chip. They operate in the 902-928MHz frequency band and utilize an industrial-grade, high-precision, active temperature-compensated crystal oscillator. By adding an RF front-end module (RF FEM), these modules improve anti-interference performance and communication range, further widening the gap with products using FSK and GFSK modulation methods.
