1.Overview
1.1 Introduction
E78-400M22S is a SoC LoRa RF module designed by Ebyte, working at
410 ~ 493MHz (default is 433MHz) with max transmitting power of 22dBm.
With ASR company's ASR6501 chip, which is an ultra-low power LoRa
integrated single chip SoC, Semtech advanced low power LoRa Transceiver
SX1262, and integrated a Cypress 32-bit cor-m0 + low power MCU, Flash
capacity 128kB, SRAM capacity 16kB, ultra-small size, ultra-low power, the
module supports LoRaWAN, LinkWAN protocol standards, suitable for a variety of Internet of things application
scenarios. It is currently the best choice for LPWAN application chips.
E78-400M22S is a hardware platform and cannot be used directly. Users need to conduct secondary development
(Ebyte can customize standard LoRaWan and Alibaba linkWan nodes for you).
