ATmega128A Minimum System Core Board

Overview

ATmega128A Minimum System Core Board / Adapter Plate

Product Overview

Unlock the full potential of the powerful 8-bit AVR architecture with the ATmega128A Adapter Plate. Dealing with fine-pitch Surface Mount Devices (SMD) can be a significant hurdle during rapid hardware prototyping. This breakout board solves that problem by pre-mounting a genuine Atmel ATmega128A microcontroller (TQFP-64 package) onto a high-quality PCB, cleanly breaking out all 64 pins to standard 2.54mm through-holes.

Whether you are translating complex circuit schematics into physical hardware, building out comprehensive sensor data pipelines, or simply expanding the microcontroller toolkit, this adapter plate provides a robust and breadboard-friendly foundation for your next embedded systems project.

Key Features

• Pre-Soldered ATmega128A: Powered by the Atmel ATmega128A-AU chip, providing a massive 128KB of in-system programmable flash memory, 4KB EEPROM, and 4KB SRAM for code-heavy applications.

• Comprehensive Pin Breakout: All 64 pins of the delicate TQFP package are routed to standard 2.54mm pitch headers, entirely eliminating the need for precise SMD soldering on your end.

• Clear Silkscreen Labeling: The board features highly visible numerical pin grouping (as seen in ATMEGA128BA.jpg) to prevent wiring errors and streamline your prototyping workflow.

• High-Quality PCB: Manufactured with a durable fiberglass substrate and clean trace routing to ensure stable performance even in electrically noisy environments.

Common Applications

• Embedded Systems Development: An ideal core board for building custom AVR-based logic controllers and industrial automation prototypes.

• Rapid Prototyping: Transition seamlessly from digital schematics to physical breadboard testing without fabricating expensive custom PCBs.

• Sensor Integration: Leverage the ATmega128A's extensive I/O capabilities (53 programmable I/O lines) and 8-channel, 10-bit ADC to interface with large arrays of analog and digital sensors.

• Custom Tooling: Develop specialized testing jigs or localized processing units that require more I/O and memory than standard development boards offer.

Technical Specifications

Prototyping Notes

To begin flashing firmware to this adapter plate, you will require an external AVR ISP (In-System Programmer) or JTAG interface. Because this is a bare-metal breakout board, ensure your power supply logic is properly regulated and matches your connected peripherals, especially when bridging communication between this board and sensitive 3.3V sensors or other logic controllers on your workbench.
