[Introduction]:E28-2G4M12SX is a 2.4GHz radio frequency transceiver module designed and produced by Ebyte Company. It has long communication distance and extremely low current consumption in low power consumption mode. This module is a small size chip type (pin pitch 1.27mm). This series uses 52MHz industrial-grade high-precision low-temperature drift active crystal oscillator to ensure its industrial characteristics and stable performance.
