ELEGOO 3pcs Breadboard 830 Point Solderless Prototype PCB Board Kit (Pack of 2)

The information below is per-pack only; THREE FULL-SIZE BOARDS FOR MORE PROJECT SPACE - Keep a clock, sensor station and controller test circuit assembled at the same time, give each STEM team its own board or join boards side by side for larger classroom, robotics and maker prototypes; 830 TIE POINTS WITH FOUR POWER RAILS - Each board provides a 630-point terminal area plus two 100-point distribution strips, a center channel for compatible DIP integrated circuits and printed letters, numbers and colored rail guides for easier circuit tracing; BUILD, TEST AND REWIRE WITHOUT SOLDERING - Insert resistors, LEDs, capacitors, transistors, sensors, jumper wires and compatible controller connections, then change the circuit as lessons or designs evolve; suited to family learning, electronics labs and rapid debugging; MOUNT OR EXPAND YOUR WORKSPACE - Peel the self-adhesive backing to secure a finished prototype to a clean flat surface, or use the side clips to align compatible boards; wide ESP32-style development boards may cover adjacent rows, so place them across two boards when needed; START WITH RELIABLE CONNECTIONS - Use straight 21-26 AWG leads, insert parts vertically without forcing oversized pins and verify row and rail continuity before applying power; jumper wires, components, controller boards and power modules are not included
