[Introduction]:E22-400T30E est une nouvelle génération de module sans fil LoRa. Il est conçu sur la base du module de port série sans fil (UART) de la puce RF de SEMTECH et du schéma de puce SX1268 original de SEMTECH. Il a une variété de méthodes de transmission, fonctionne dans la bande de fréquence (410,125 ~ 493,125 MHz) (par défaut 433,125 MHz), technologie de spectre étalé LoRa, sortie de niveau TTL, compatible avec la tension de port IO 3,3 V et 5 V.

Pin numberPin namePin OrientationPin usage
1AUXOutput

It is used to indicate the working state of the module; the user wakes up the external MCU, and outputs a low level during the power-on self-test initialization; (can be left floating)

2VCCEnter

Power input 5.0V

3M0

Input (very weak pull-up)

Cooperate with M1 to determine the 4 working modes of the module(can not be suspended, if not used, it can be grounded)

4GND-

Power reference ground

5M1

Input (very weak pull-up)
