When building a prototype, the issue of power supply often arises. Without a stabilized power supply, it's nearly impossible to power multiple circuits simultaneously. This is why I offer a low-cost solution to power microcontroller-based circuits. With this project, all that's needed is to power the board (via a transformer socket), and the board will be able to provide a regulated voltage and a current of up to 2 amps!
The ESP family includes microcontrollers designed for developing connected projects. Their main advantage is that they are compatible with the Arduino environment. They also allow for larger projects, as they are more powerful. But is it really worth using the Arduino environment to program these devices?
