We are pleased to introduce our new open source project - Universal PCB for ATMEGA 644/1284 microcontroller family, which offers unique flexibility to use both DIP-40 and TQFP-44 packages.
Key features of the project
- Versatile: Two types of packages (DIP-40 and TQFP-44) on one board.
- Reset control: Keep one microcontroller in reset state to use the other.
- Easy upgradeability: Unique hardware upgradeability of your device thanks to the DIP package
- Open Source: The project is distributed under the MIT license
- Optimized design: Designed for dual-layer PCBs with adaptability
Practical application
Our solution is particularly useful for:
- Developers working with prototypes
- Educational projects
- Small batch production
- Experimental development
Technical realization
The board is designed to maximize port compatibility between both types of packages. Switching between microcontrollers is done via RESET line control, which ensures reliable operation of the system.
Availability
All project materials, including schematics and PCB files, are available on GitHub. We welcome community participation in the development of the project and look forward to your suggestions for improvement.
