The outer shell is made of insulating material, and the inner part is a built-in circuit board. When the building blocks are assembled on the base plate, they will immediately light up.
Use your imagination to build robots, towers, art sculptures, and more, and light them up.
Infinite base plate, which can connect more base plates and provide greater operating space.
Colorful and soft lighting with built-in LED lights that emit light through plastic, providing rich and soft colors.
The rechargeable base plate connects the base plate to the battery compartment and can be charged through a metal contact piece.
Environmentally friendly materials ABS material is environmentally friendly and children can safely assemble building blocks.
When you don't need the battery box, you can remove it. Add a switch to the backplane and power it through a USB cable
Different switches with USB power supply (different collections include different switches) Please note: USB power and battery cannot be used at the same time Self-locking switch (YS2981A: 20 block sets) Please connect the power supply with a USB cable first, and then press the switch, the blocks on the bottom plate will light up and press the switch again, and the light will turn off Touch switch (YS2981B: 40 block set) Please connect the power supply with a USB cable first, then press the switch, and the blocks on the bottom panel will light up. When you keep pressing the switch, the light will get dimmer or brighter. Press the switch again and the light will turn off. Human Sensor Switch (YS2981:60 Building Block Group) Human body sensor switch is also called passive infrared sensor switch. It measures infrared light emitted from objects in its field of view. Commonly used in security alarm and automatic lighting applications. Please connect the power supply with a USB cable first. When someone enters the field of view, it measures infrared radiation and automatically lights up the blocks. When someone leaves, the blocks light up.
