MCU

Accelerate your embedded hardware development with ready-to-use MCU schematic templates for KiCAD. These modules are professionally designed to include all essential circuitry for popular microcontrollers like ESP32, STM32, and ATmega families — enabling rapid prototyping and reliable design reuse.

Each schematic module includes:

  • Fully labeled MCU symbol with named I/O pins
  • Proper power supply decoupling (ceramic + bulk caps)
  • Required reset circuitry, boot configuration resistors, and crystal oscillator setup
  • Clearly defined programming/debug interface (e.g., SWD, JTAG, UART)
  • Labeled nets for GPIOs, power domains, and I/Os
  • Optionally includes external flash, antenna matching (for ESP32), or boot mode selectors

Examples of included MCUs:

  • ✅ ESP32-WROOM-32D with antenna circuitry, flash, and EN/IO0 setup
  • ✅ STM32F030 with HSE oscillator, NRST, and SWD pins
  • ✅ STM32F103 with crystal setup, boot pins, and USB-ready pins
  • ✅ (Upcoming) ATmega328P, RP2040, PIC18F4550, etc.

These templates follow industry best practices and are ideal for:

  • Embedded system designers
  • Product developers working with STM32, ESP32, or AVR
  • Rapid prototyping and professional board development
  • KiCAD users building their own custom MCU boards
