The Super:bit Expansion Board (V1.0 AM-003) is a high-performance, all-in-one robotics and I/O expansion module specifically designed for the BBC micro:bit. In 2026, it is recognized as one of the most versatile bases for building advanced robotic vehicles, robotic arms, and complex IoT systems.
Long Product Description
The Super:bit V1.0 (AM-003) is engineered to solve the most common challenges in micro:bit robotics: power management and multi-device control. Unlike basic expansion boards, the Super:bit integrates a high-current motor driver and a dedicated lithium battery management system on a single PCB. It allows the micro:bit to simultaneously drive 4 DC motors and 8 servos, making it capable of powering complex machinery like Mecanum wheel rovers or bipedal robots.
Designed for durability and ease of use, the board features color-coded headers for sensors and high-quality terminal blocks for motors. It also includes built-in addressable RGB LEDs (NeoPixels) and a microphone/buzzer suite, providing a rich sensory experience out of the box. For business and educational purchasers, the AM-003 model is a “complete ecosystem” board that reduces the need for additional shields, lowering the total cost of robot kits while increasing reliability.
Key Features
- Integrated Power Management: Features a built-in 18650 lithium battery slot with a charging circuit and 5V/2A boost output for high-torque peripherals.
- High Motor Density: Controls up to 4 DC motors (or 2 stepper motors) and 8 servos at the same time.
- Full I/O Breakout: All micro:bit pins are accessible via standard 3-pin G-V-S (Ground-Voltage-Signal) headers.
- Built-in Sensory Peripherals: Includes 4x addressable RGB LEDs (WS2812B), a buzzer, and an I2C interface for OLED displays.
- Safety Protection: Equipped with reverse polarity protection, over-current protection, and a low-battery warning.
- Sturdy Design: Includes four M3 mounting holes and is compatible with Lego-style brick building for rapid physical prototyping.
