EBYTE E28-2G4M12SX SX1281 12.5dBm 2.4G Lora Module Spread Spectrum Wireless Module spi Interface Ancor GFSK rf module

[Introduction]：E28-2G4M12SX is a 2.4GHz RF transceiver module designed and produced by Ebyte, with long communication distance and extremely low current consumption in low power consumption mode. This module is a small-volume patch type (pin pitch 1.27mm). This series adopts 52MHz industrial-grade high-precision low-temperature drift active crystal oscillator; it guarantees its industrial characteristics and its stable performance. It can be used in smart homes, security systems, location tracking, wireless ranging, wearable devices, smart bracelets and health management, etc. [Chip solution]：SX1281 [Transmission power]：12.5dBm [Communication distance]： 3km [Communication interface]：SPI  Main Parameters model Remark Power supply voltage (V) 0～3.6 Exceeding 3.6V permanently burns out the module Blocking power (dBm) 10 Less chance of burning when used at close range Working temperature (℃) -40～+85 industrial grade  Main Parameters Parameters Remark Working voltage (V) 1.8～3.6 ≥3.3V guaranteed output power Communication level (V) 3.3 Risk of burning with 5V TTL Working temperature (℃) -40～+85 industrial design Working frequency band (MHz) 2400～2500 Supports ISM bands Power Consumption Emission current (mA) 45 Instantaneous power consumption Receive current (mA) 10 Sleep current (μA) 2 software shutdown Maximum transmit power (dBm) 12～14 Receiving sensitivity (dBm) -128～-130 LoRa receiver sensitivity with CR=4/5 and high sensitivity mode enabled 1 SF12,BW=203kHz communication rate LoRa（bps） 0.595k～253.9k User Programmable Custom FLRC（bps） 1.3M User Programmable Custom GFSK（bps） 125k～2M User Programmable Custom Main Parameters Description Remark Reference distance 3000m Clear sky, antenna gain 5dBi, antenna height 2.5 meters, air rate 1kbps FIFO 256Byte The maximum length of a single send Crystal frequency 52MHz ±10ppm/11pF Modulation LoRa (recommended) GFSK Mode, FLRC Mode, LoRa Mode Encapsulation SMD Interface 1.27mm Communication Interface SPI 0～10Mbps Dimensions 17.8mm×15mm Antenna interface IPEX Net product 1.1±0.1g
