Introduction
E41-400M20S is an ultra-high cost-effective wireless data transmission module. It is based on AMICCOM's A7139 radio frequency chip, and it has the characteristics of small size and low power consumption. E41-400M20S works in 425MHz ~ 470MHz, it supports the maximum 20dbm transmission power, users can set lower output power, so as to save power. At the same time, this module is especially suitable for battery power supply. In 433MHz frequency band, the power consumption of RX mode can be reduced to 3.8ma. This module adopts SPI interface. Since this module is a pure RF transceiver module, it needs an external MCU to drive and a dedicated SPI debugging tool.
