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.
