Welcome to your new project. Imagine what you can build here.

An example development and reference design for the ESP32 microcontroller.

A simulated blinking LED circuit using an astable multivibrator a.k.a "flip-flop" as a square wave generator. It also includes PCB layout of the project.

A preliminary design for developing SMT32F4x series based project that’ll help you get started faster.

A simulated circuit that demonstrates how diodes in a bridge configuration convert an AC voltage to DC voltage.

Two separate simulated circuits which demonstrate how step-up and step-down type transformers work.
