2pack mini solderless breadboards, 170 tie points each, in blue. Compact and reusable prototyping boards designed for quick circuit building and testing with Arduino and other microcontroller projects. Key benefits Fast prototyping: solderless design lets you assemble, modify, and test circuits without soldering. Spacesaving: mini form factor fits into small work areas and enclosures while still providing 170 tie points for common circuits. Reliable connections: sturdy plastic construction and reliable metal contact strips provide consistent electrical connections for jumper wires and components. Versatile compatibility: works with Arduino boards, development kits, and standard jumper wires and components for easy integration into hobby and educational projects. Two boards included: run two parallel projects, expand a single prototype, or keep a spare for parts and testing. Features and attributes Function: reusable solderless breadboard for building and modifying electronic circuits quickly and without permanent assembly. Tie points: 170 tie points per board for laying out component connections and jumper routing. Size: mini footprint ideal for compact projects and portable setups. Material and construction: robust plastic base with metal contact strips to hold leads and jumper wires securely. Performance: consistent contact retention for lowcurrent prototyping and iterative testing. Typical use scenarios Arduino sensor prototyping: connect sensors, resistors, and jumpers to test code and hardware interactions before final assembly. Classroom and training labs: small, safe boards for students to learn circuit basics and practice handson electronics. Quick repairs and experiments: try alternative component values or circuit layouts without desoldering or permanent changes. What you get Two blue mini solderless breadboards, each with 170 tie points, ready to use for prototyping, teaching, and testing electronic circuits.
