Arduino UNO Proto Shield Prototype Expansion Board with Mini Breadboard

UNO PROTO SHIELD PROTOTYPE EXPANSION BOARD is an essential circuit prototyping expansion shield designed for Arduino UNO development boards. Supplied with a 170-point mini solderless breadboard, it allows makers and engineers to rapidly build and test custom circuits using through-hole solder pads, surface-mount component footprints, or temporary plug-in breadboard connections without permanently altering their Arduino hardware.

Key Features:

• SYB-170 Mini Breadboard Included: Comes with a self-adhesive 170-tie-point mini solderless breadboard that attaches directly to the prototyping area.
• Dual Prototyping Options: Solder components permanently onto the standard 0.1-inch grid or use the breadboard for temporary jumper wire prototyping.
• Dedicated SMD Footprint: Onboard surface-mount soldering area accommodating SOIC-14 IC packages for prototyping compact SMD circuits.
• Dual User LEDs and Buttons: Features 2 onboard general-purpose LEDs (Red and Green with current-limiting resistors) and a secondary tactile pushbutton.
• Pass-Through ICSP Header: Includes a 6-pin ICSP pass-through header allowing seamless connection of SPI shields and AVR programmers.
• Full Pin Breakout: All Arduino UNO digital, analog, power, and ground pins are brought out to neighboring rows of soldering eyelets.
