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

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.

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