The STM32F4 Black-Pill, a powerful and versatile microcontroller, offers promising potential for IoT applications when integrated with LoRa modules like EByte’s E32, E22, and E220. In this article, we’ll examine the Shield I use for rapid prototyping that supports all the LoRa modules described.
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 want to simplify the use of external SPI flash memory with my Arduino MKR WiFi 1010, therefore, I have created, a simple Shield PCB to achieve my purpose faster.
For me, It’s very important the network connection and network limitation on STM32F4 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.

I’m going to publish my LoRa shield for WeMos LOLIN32. This is one of my favorite microcontrollers, and until now, I have been using a simplified version of shield for rapid prototyping, but in the end, I created a more complete version, and I share it with everyone.
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.
