ESP32-S3, SX1262 LoRa with Duty Cycle, Wake on Radio, and Deep Sleep

AB9NQ-William

GitHub project "EoRa PI Foundation" receiver has 175 µA average current consumption using SX1262 LoRa Duty Cycle and Deep Sleep. Current measurement images; done with Nordic Power Profiler Kit II. 

Project is a web based, remote load controller that wakes by LoRa radio, turns on a load, calls radio sleep mode, sets an external0 wake timer.  Timer expires, wakes up, load is turned off, devices go to sleep and await for next web request; then cycle repeats

Ideal Applications

  • Remote equipment control in field deployments (months of operation)
  • Battery-powered IoT sensor networks
  • Agricultural automation systems
  • Emergency/backup communication systems
  • Environmental monitoring with long-term deployment
  • Camera activation systems (original use case)

    Yes, well documented with examples; board config file and utilities file that help with programing.  No deep sleep examples; however, they do provide a RadioLib Interrupt example that was a help in the project.  I leaned heavily on Claude.  SX1262 was new to me had worked with e220 in another similar project.  One thing about this board; only 26 GPIO pins are exposed, not all are io useable.  Claude created a table with physical pin number, GPIO number, RTC number, Wake capable noted, and usage note; very useful.  Included in my project Docs folder.  Real "treasure" of documentation for anyone working with "EoRa-S3-900TB from EbyteIoT.com.  Great development board under $20... many features!  Another great feature built-in LiPo battery charger!

  • Interesting module.. even has a built-in display! 

    I've tried one or two smaller/simpler eByte modules in the past; they make nice stuff.
