From the project
A compact, self-contained development board for the 8051 microcontroller family (AT89x51xxP), designed in KiCad — built to run 8051 firmware on the bench with nothing more than a barrel-jack power supply and a USB-to-serial adapter.
A compact, self-contained development board for the 8051 microcontroller family (AT89x51xxP), designed in KiCad — built to run 8051 firmware on the bench with nothing more than a barrel-jack power supply and a USB-to-serial adapter.
Purpose This repository contains the full KiCad design (schematic, PCB layout, and fabrication outputs) for a standalone 8051 development board. It's built around the classic AT89x51xxP DIP-40 microcontroller and includes on-board power regulation, a crystal oscillator, reset circuitry, and breakout headers — everything needed to power up and program an 8051…
