About the ATmega328P-Minimal-Development-Board

ATmega328P-Minimal-Development-Board is an open source AVR/Arduino PCB design by moaazzz-h, published on GitHub under the MIT license. It is a 2-layer board measuring 82.9 × 62.9 mm, with 24 components from 17 distinct parts.

Its main chip is the ATmega328-P, from the AVR/Arduino family. Other key parts include the LM7805_TO220. By type, the board carries 8 capacitors, 6 connectors, 3 diodes, 3 resistors, 2 ICs and 1 crystal.

It belongs with the dev boards & breakouts and usb & debug tools designs in this gallery.

From the project

Minimal ATmega328P development board with onboard 5V regulation, ISP & FTDI programming headers, reset circuit, status LEDs, and full I/O breakout — no Arduino required. Designed by Moaaz Hesham.

A minimal, breadboard-free development board built around the ATmega328P-PU, designed by Moaaz Hesham. It provides onboard power regulation, ISP/FTDI programming headers, a reset circuit, status LEDs, and fully broken-out I/O — everything needed to prototype and program the ATmega328P without an Arduino.

- 5V regulated power supply — barrel jack or 2-pin screw terminal input, reverse-polarity protection, LM7805 linear regulator - ATmega328P-PU in DIP-28 package with 16 MHz crystal oscillator - ISP programming via standard 6-pin AVR-ISP header - FTDI/UART programming & bootloader support via…
