An essential factor of our micro-controllers is power consumption. As usual, I started to analyze that aspect without entering the detail for sleep mode but with some alternative solutions offered by the micro controller.
Now we are going to examine the management of clock frequencies of STM32F4 series.

Mastering clock source and frequency management is vital in STM32 development. The STM32F1, or “Blue Pill,” provides several options to balance device performance and power saving. The STM32F1 sources its clock from an internal RC oscillator (HSI), an external crystal oscillator (HSE), or a Phase Locked Loop (PLL) that can amplify the HSI or HSE for higher frequencies. By carefully choosing and setting up these clock sources, you can greatly optimize your device’s power consumption.
In this guide, we aim to explore the many aspects of interfacing the I2C protocol with the popular ESP8266 microcontroller. As a versatile and powerful component, the ESP8266 has found its place in numerous IoT projects, primarily due to its WiFi capabilities and low cost.
Here an article that provides a step-by-step guide for getting started with MicroPython development on the ESP8266 and ESP32 boards using the Thonny IDE. The article covers how to flash MicroPython firmware onto the board and how to connect to the board using Thonny’s MicroPython plugin. Additionally, the article includes an example project that demonstrates how to control an LED connected to the board using MicroPython code.

This guide focuses on using MicroPython with ESP8266 and ESP32 microcontrollers, two popular choices for IoT and embedded systems. By understanding the standard instruments available with MicroPython, such as Python, esptool, ampy, PuTTY, and screen, you can quickly and easily build projects for these powerful devices. This guide will provide an overview of each tool and how to use them effectively, so you can take full advantage of the capabilities of your ESP8266 or ESP32 microcontroller.
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.
