ProtoShield Prototype Expansion Board with Mini Breadboard for UNO-R3

ProtoShield Prototype Expansion Board with Mini Breadboard for Arduino UNO R3

A ProtoShield prototype expansion board compatible with Arduino UNO R3 and Duemilanove, featuring an integrated SYB-170 mini breadboard attached via double-sided tape. All Arduino pins and power supplies are broken out to the shield, allowing you to solder components directly to the prototyping area or connect them through the mini breadboard — the fastest way to build permanent or semi-permanent Arduino circuits without designing a custom PCB.

The shield includes two onboard LEDs and two button circuits for immediate use in projects, plus clearly labeled pin headers for all Arduino UNO digital and analog pins.

Key Features

• Compatible boards: Arduino UNO R3, Duemilanove
• Mini breadboard: SYB-170 (170 tie-points), attached via double-sided tape
• Onboard components: 2× LEDs, 2× button circuits
• Pin breakout: All digital, analog, power, and GND pins
• Prototyping area: Solderable pads for permanent component mounting
• RoHS compliant

Why Choose This ProtoShield?

• ✅ Mini breadboard included — prototype without soldering, then solder for permanence
• ✅ All pins broken out — full access to every Arduino UNO pin
• ✅ Onboard LEDs & buttons — ready-to-use I/O for immediate project use
• ✅ Solderable prototyping area — build permanent circuits directly on the shield
• ✅ Stacks directly on Arduino UNO — no wiring required, clean and compact

Typical Applications

• Rapid Arduino UNO circuit prototyping and iteration
• Building permanent Arduino circuits without custom PCB design
• Electronics classroom and STEM education projects
• Sensor and actuator integration with Arduino UNO
• LED and button control circuit development
