Eight years ago, I decided to create a world record with a tiny LoRa transmitter. The distance? 202 kilometers. Today, I’m trying something even more ambitious — with this small ESP32 module.
Its Wi-Fi range usually covers just your home or maybe 50 meters around it. But this time, the goal is far more extreme. Can we send its signal 36,000 kilometers?
That’s nearly once around the world! If I’m successful, I’m pretty sure this record will be valid for a long time. The race is on!
You can use a solar-aware LiPo charging circuit, such as the MCP73871, BQ24074, or Adafruit’s USB/DC/Solar LiPoly charger. These can intelligently manage solar variability and protect both the LiPo and ESP32.
