The E78 series products are radio frequency transceiver modules with multiple frequency bands 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 spacing 1.1mm).
The E78 series products use ASR's ASR6505 chip, which is a single-chip SoC integrated with ultra-low power LoRa, using Semtech's advanced low-power LoRa Transceiver SX1262, and integrates a STM8L152 low-power MCU, Flash capacity 64kB, SRAMCapacity 4kB, EEPROM capacity 2K, small size, ultra-low power consumption, support LoRaWAN, LinkWANmultiple protocol standards, suitable for a variety of Internet of Things application scenarios, is currentlythebestchoice for LPWAN application chips.
The E78 series products are hardware platforms and cannot be used independently. Users need tocarryoutsecondary development. (We can customize standard LoRaWan and Ali linkWan nodes) Features: Under ideal test conditions, the communication distance can reach 5.5km; The maximum transmit power is 22dBm, and the software is multi-level adjustable; Support license-free ISM 868/915MHz frequency band; Support multiple modulation modes (GFSK Mode, LoRa); Support 1.8～3.7V power supply, power supply greater than 3.3V can guarantee the best performance; Industrial standard design, supporting long-term use at -40～+85℃; Dual antennas are optional (IPX/PCB), which is convenient for users to develop and integrate; Based on the ASR6505 chip development, users can directly use it for secondary development.
Applications: Smart home and industrial sensors, etc.; Security system, positioning system; Wireless remote control, UAV; Wireless game remote control; Healthcare products; Wireless voice, wireless headset; Automotive industry applications It is the perfect solution for reliable, low-power communication devices, combining cutting-edge technology and robustness with ease of use and high-end performance. Get the most out of your LoRaWAN and LinkWAN applications with the ASR6505 LoRa Wireless Module SoC MCU STM8L152 868MHz 915MHz E78-900M22S1A 22dBm 5.5km Low Power Consumption Wireless Transceiver.
