- Introduction to modifying breadboards for wider microcontrollers like Raspberry Pi Pico and ESP32.
- Standard breadboards modified by removing metal spring contacts and reusing them in a 3D-printed body.
- New design maintains 63×5 contact layout with vertical power rails, leaving four accessible holes per pin.
- Two versions available: one for Raspberry Pi Pico (17.78 mm pin spacing) and another for ESP32 (25.4 mm pin spacing).
- Materials needed include a standard breadboard for contacts, 3D-printed parts, optional screws or glue, and basic tools.
- Detailed steps provided from disassembling the original breadboard to installing contacts and attaching the bottom plate.
- Print quality and tolerances are crucial; recommendations for printer settings to achieve fine details.
- Instructions for inserting the microcontroller and using the modified breadboard for prototyping.
- All design files (Fusion 360, STL, 3MF) available on GitHub for customization and further development.
