Unleashing IoT Potential: Integrating STM32F1 Blue-Pill with EByte LoRa E32, E22, and E220 Shields

The Internet of Things (IoT) landscape is evolving at a rapid pace, leading to an increased demand for robust and scalable communication technologies. LoRa, or Long Range, is one such technology that has gained significant traction in recent years. In this article, we will delve into the integration of STM32F1 Blue-Pill, a highly capable microcontroller, with EByte LoRa E32, E22, and E220 shield modules, which are popular for long-range, low-power applications.

I start using STM32 microcontrollers, and I find they are of superior quality. But I need a prototyping board to do my work faster.

I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify to the server.

Now we put all the Client components in the relative Case.
