Chengdu Ebyte Electronic Technology Co., Ltd.

1. Overview

1.1 Brief introduction

E19-433M30S is 1W SMD wireless module working at 433MHz,
developed based on chip SX1278 from Semtech.
Due to the use of the imported SX1278 as the core of the module,
with PA and LNA its sensitivity and stability are largely improved when
tx power is 1W.Compared with the FSK、GFSK products, it has made
great progress in receiving current, receiving sensitivity, transmitting
power, receiving rate range and anti-interference ability. The module is
aimed at smart home, wireless meter reading, scientific research and
medical, and medium and long distance wireless communication
equipment. Since RF performance and component selection are in accordance with industrial standards, and the product
has obtained FCC, CE, RoHS and other international authoritative certification reports, users do not need to worry about
its performance. High precision 32MHz crystal is used.
Since the module is a pure RF transceiver module, you need to use the MCU driver or a dedicated SPI debug tool.
