micro:bit TPBot Edu Car Kit

The ELECFREAKS TPBot EDU Car Kit is a feature-rich educational robot car designed for use with the BBC micro:bit. Developed to support STEAM learning, it helps students and hobbyists explore programming, electronics, and robotics through engaging hands-on activities.

The TPBot EDU comes pre-equipped with a line-following sensor and ultrasonic distance sensor, enabling immediate obstacle avoidance and path-tracking capabilities — no external modules required. Precision encoder motors and a built-in 6-axis gyroscope allow for stable navigation, straight-line driving, and smooth turns.

In addition to its onboard sensors, the robot features 8 expansion ports to support further development:

• 2 sensor ports (RJ11) for additional modules
• 2 I2C ports (RJ11) for components like displays or environmental sensors
• 4 servo ports for robotic arms or custom mechanical extensions

It includes a rechargeable 7.4 V Li-ion battery, offering around 2–4 hours of continuous use per charge. Charging is via USB-C (5 V, max. 2.1 A), with a full charge typically completed in about 70 minutes.

LEGO-compatible mounting points encourage creative design, while support for MakeCode and Python ensures accessibility for beginners and advanced learners alike.
