Product Descriptions

E28-2G4M20S is a 2.4GHz bluetooth module designed by Chengdu Ebyte,with long distance and ultra-low power consumption. E28-2G4M20S is small-sized SMD module(pin spacing 1.27mm),built-in PCB antenna and IPEX antenna. High precision 

52MHz crystal is used. Based on the original imported RF chip SX1278 from Semtech,the IC SX1280 features multiple physical layers and various modulating methods such as LoRa, FLRC and GFSK, the special modulating methods and

processing ways enable longer operating range under LoRa and FLRC modulating methods, and the GFSK method covers BLE protocol. 

The outstanding ultra-low power consumption and the DC-DC and Time-of-Flight on chip make the chip much more capable for smart home, security system, tracking and locating, wireless distance measuring, wearable electronics, smart bracelet and 

health management & etc. SX1280 supports RSSI,users need to conduct a secondary development based on their own demands;SX1280 also integrates time of flight for ranging functions. Since the module is a pure RF transceiver module, you need to 

use the MCU driver or a dedicated SPI debug tool.
