Ebyte E32-400M33S 16km LoRa Spread Spectrum Technology 33dBm SX1268 RF Transceiver Module 433/470MHz Lora wireless module

E32-400M33S SX1278 chip Lora module 433/470MHz LoRa spread spectrum technology SPI hardware module [Chip solution]：SX1278 [Transmitting power]：33dBm [Communication distance]：16km [Product size]：24*38.5m [Introduction]：E32-400M33S is a 410~493MHz SMD LoRaTM wireless module with a maximum transmitting power of 2W, which is independently developed based on the SX1278 produced by Semtech in the United States. As the imported SX1278 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 transmitting power reaches 1W while the receiving sensitivity is further improved, and the overall communication stability is greatly improved compared with products without power amplifiers and low noise amplifiers. This module is mainly aimed at smart homes, wireless meter reading, scientific research and medical treatment, as well as medium and long-distance wireless communication equipment. Send Inquiry Purchase Official Store Alibaba Aliexpress 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 LNA may burn if used at close range Working temperature (℃) -40 85 Industrial grade Main parameters Performance Remark Minimum value Typical value Maximum value Working voltage (V) 3.3 5 5.5 >5.5V can cause permanent damage to the module; Communication level (V) - 3.3 - - Working temperature (℃) -40 - 85 Industrial grade design Working frequency band (MHz) 410 - 493 - Power consumption Emission current (mA) - 1100 - - Receive current (mA) - 19 - - Sleep current (μA) - 2 - - Maximum transmit power (dBm) - 33 Receiving sensitivity (dBm) -123 -124 -125 The air rate is 1.2kbp Main parameters describe Remark reference distance 16Km In a clear and open environment, the antenna gain is 5dBi, the antenna height is 2 meters, and the air rate is 2.4kbps.
