Ebyte E220-400M33S 16km 33dBm LoRa Spread Spectrum Technology SPI RF Module 433/470MHz LLCC68 chip LoRa wireless module

E220-400M33S LLCC68 433/470MHz LoRa Spread Spectrum Technology SPI Hardware Module [Operating frequency]：410~493MHz [Transmitting power]：33dBm [Communication distance]：16km [Product size]：38.5*24mm [Introduction]：E220-400M33S is based on the new generation of LoRaTM RF chip LLCC68 produced by Semtech. It is independently developed with a maximum power of 2W and is suitable for 433/470MHz SMD LoRaTM wireless modules. It uses an industrial-grade high-precision 32MHz crystal oscillator. Since the imported LLCC68 is used as the core of the module, a power amplifier (PA) and a low-noise amplifier (LNA) are built in on the original basis, so that the maximum transmission power reaches 2W and the receiving sensitivity is further improved. The overall communication stability is greatly improved compared to products without power amplifiers and low-noise amplifiers. Send Inquiry Purchase File DownloadsCompare Specification Parameters Pin Definition Order Way File Downloads Series Products Main parameters performance Remark minimum value maximum value Supply voltage (V) 0 5.5 Exceeding 5.5V will permanently burn the module Blocking power (dBm) - 10 Less likely to be burned if used at close range Working temperature (℃) -40 85 Industrial grade Main parameters performance Remark minimum value Typical value maximum value Working voltage (V) 3 5 5.5 ≥5V guaranteed output power Communication level (V) - 3.3 - Using 5V TTL risks burning out Working temperature (℃) -40 - 85 Industrial grade design Working frequency band (MHz) 410 433/470 493 Support ISM frequency band Power consumption Emission current (mA) - 1200 - Instantaneous power consumption Receive current (mA) - 12.5 - Sleep current (μA) - 1 - Software shutdown Maximum transmit power (dBm) 32.5 33 33.5 Receiving sensitivity (dBm) - -129 - -124dbm,BW_L=125kHz,SF = 7,LORA TM ;-129dbm,BW_L=125kHz,SF = 9,LORA TM ;-121dbm,BW_L=250kHz,SF = 7,LORA TM ;-129dbm,BW_L=250kHz,SF = 10,LORA TM ;-117dbm,BW_L=500kHz,SF = 7,LORA TM ;-127dbm,BW_L=500kHz,SF = 11,LORA TM ; Communication speed rate GFSK（bps） 0.6k -121dbm,BW_L=250kHz,SF = 7,LORA TM ; 300k User programmable customization LoRa（bps） 1.76k -121dbm,BW_L=250kHz,SF = 7,LORA TM ; 62.5k User programmable customization Main parameters describe Remark Measured distance 16km Sunny and open space, antenna gain 3.5dBi, antenna height 2.5 meters, air rate 2.4kbps FIFO 256Byte Maximum length of a single send Crystal frequency 32MHz Passive crystal oscillator, recommended 24pF Modulation method LORA It is recommended to use LORA modulation method Packaging method SMD type -121dbm,BW_L=250kHz,SF = 7,LORA TM ; Interface mode 2.54mm stamp hole Communication interface SPI 0~10Mbps Overall dimensions 38.5*24mm -121dbm,BW_L=250kHz,SF = 7,LORA TM ; RF interface Stamp hole/IPEX Equivalent impedance is about 50Ω weight 5.85g -121dbm,BW_L=250kHz,SF = 7,LORA TM ;
