Boards, power and components for your next robot

Everything here is chosen for Raspberry Pi and Arduino builds: a starter kit for first robots, a Pi 4 board for heavier projects, batteries and a charger to keep things running, and the motor drivers, sensors and servos that make a robot move. Filter by category, compare the key specs below, and add several parts to your cart in one pass.

Kit or parts

Starter kit or individual parts?

Both routes end with a working robot. The right one depends on how much you want to plan yourself.

Questions before you order

Are your components compatible with both Raspberry Pi and Arduino?

The Dual H-Bridge Motor Driver works with Pi GPIO and Arduino, and the HC-SR04 is a standard module that connects to any microcontroller. One detail for Pi users: the HC-SR04 echo pin outputs 5V, while Pi GPIO pins expect 3.3V, so add a simple resistor voltage divider on that line.

Do the starter kits include batteries and chargers?

The Raspberry Pi Robot Starter Kit is listed with a Pi 4, motor driver, sensors and chassis. Check the product page for the exact contents. If you need power, the 3000mAh Li-Ion Battery Pack and USB-C Smart Charger 3A are in the Power & Charging category.

Can I run the Pi straight from the 7.4V battery pack?

No. The Raspberry Pi 4 needs a regulated 5V supply, so use a 5V regulator or buck converter between the pack and the board. The motor driver can take the battery voltage for the motors. Battery selection for robotics projects covers capacity, weight and safety in more detail.

Can I power SG90 servos from the Pi?

Power the servos from a separate 5V supply and share a common ground with the Pi. Drawing servo current through the Pi's pins can cause resets or brownouts, especially when several servos move at once.

Can I buy individual parts or only complete kits?

Every part in the catalog is sold on its own, so you can buy a full kit, single components, or a mix in one order.

Do you offer bulk pricing for schools and clubs?

Send us your quantities and project through the contact page and we'll reply with what we can offer.

What is your return policy?

Returns and refunds are covered in our refund policy.
