The 9 Best Circuit Boards For Kids

For a first electronics set at eight or older, Snap Circuits Jr. SC-100 is the safe bet. Parts snap onto a plastic grid with no tools or soldering, and the manual walks through more than 100 builds, from a flying saucer to an alarm. Wirecutter picked it for being sturdy and simple. The diagrams can feel busy, and many builds are small twists on earlier ones, so a curious kid learns most by asking what happens if a part moves.

Kids who have outgrown blinking lights and want gadgets that work get more from Snap Circuits Classic SC-300. Its builds include an AM radio, a doorbell and a burglar alarm, and there are more than 300 of them, so it can last through several birthdays. Elenco backs it against defects for a year. The bigger tray of loose parts takes longer to sort and put away, and it needs a handful of AA batteries bought separately.

Kids from about age five can start with Snap Circuits Beginner SCB-20, which has fewer, simpler parts and a picture-led manual with short steps. Its 20-odd activities include a light-up fan that changes color, and Elenco says the parts and battery holder get extra childproofing for small hands. A child will run out of new ideas within a few weekends, so plan on a bigger set later. Batteries are sold separately.

Instead of a snap grid, National Geographic Epic Circuits uses chunky modules joined by short wires that click into place, which feels closer to wiring a real gadget. The book lists more than 120 projects, such as a keyboard that plays songs, a fiber-optic light show and a small copter that lifts off, and a QR code links to video help. Loose wires can tangle, and independent reviews of this set are still scarce.

Game-minded kids get a reason to keep building with Snap Circuits Arcade SCA-200, which adds a light-up number display, so circuits can keep score, count down or run a reaction game. The manual has more than 20 games among about 200 projects, and the seller lists a lifetime warranty against defects. Many builds center on the display, so the basic lessons on switches and current get a little less attention.

Builders who already own a tub of plastic bricks can wire their creations with Snap Circuits BRIC: Structures. Small adapters let Snap parts sit on standard bricks, so a model house can get a doorbell, lights or a spinning fan. The box holds a good pile of bricks and about 25 guided builds, and the pieces fit the major brick brands. Elenco's warranty runs only six months, and there is less circuit theory than in a grid-only set.

ThinkFun Circuit Maze turns circuits into a logic puzzle for one player. A challenge card shows where some tiles go, and the player places the rest so current reaches the right lights and they switch on. The 60 cards climb from beginner to expert, which makes it a good screen-free pick for puzzle fans. Tiles can lift out of the board and break the path, so a correct answer may need a firm press before it lights.

Teens and patient tweens who want the full Snap Circuits experience can go straight to Snap Circuits Pro SC-500. It adds parts for an FM radio, a voice recorder and a meter that shows what the current is doing, for more than 500 builds in all. It's a big spend for a first kit, and a younger child can feel lost in a manual this thick, so it fits best once a smaller set has proven the interest.

Set up like a small classroom lab, the Playz Circuit Board keeps a light, a fan, a buzzer and sensors fixed to one blue board, and kids connect them with short wires. The experiments explore light, sound, magnetism and touch controls, and an illustrated manual explains each one. Some sets arrive with a part that doesn't work, and the manual can be thin on why a circuit behaves as it does, so check every piece on day one.
