1 Overview

1.1 Introduction

E32-433T33D is a wireless serial port module (UART) based on SEMTECH's
SX1276 RF chip. It has transparent mode, working in the
LoRa spread spectrum technology.
SX1278 features LoRa spread spectrum, which will bring longer communication
distance, and has the advantages of concentrated power density, meanwhile it has a very
strong confidentiality. SX1278 is a milestone in the field of low-speed communication, and is favored by people in the
industry. The default air rate is 2.4kbps, the transmit power is 33dBm, with PA power amplifier and LNA low-noise
amplifier, so as to improve communication stability and extend communication distance; industrial-grade active
temperature compensated crystal oscillator is used to ensure its stability and consistency.
