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.

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.
