ELEGOO 3pcs Breadboard 830-Point Solderless Prototype PCB Board Kit

THREE FULL-SIZE BREADBOARDS: Keep multiple circuits assembled at once, give each lab group its own board or connect compatible boards side by side for larger electronics, robotics and STEM prototypes
830 TIE POINTS AND FOUR POWER RAILS: Each board includes a 630-point terminal area plus two 100-point distribution strips, with printed letters, numbers and colored rail guides to make circuit tracing easier
BUILD AND REWIRE WITHOUT SOLDERING: Insert resistors, LEDs, capacitors, transistors, sensors and jumper wires, then change connections as lessons or prototype designs evolve without soldering components in place
