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
410~441MHz (default 433MHz)
,
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.
