ELECFREAKS Petal:bit for micro:bit

The Petal Series Basic Expansion Board offers extensive connectivity options for your electronic innovation projects. It comes equipped with two analog interfaces, two digital interfaces, and four IIC interfaces, fully meeting the connection requirements of various sensors and modules. The interfaces feature a thoughtful anti-misplug design to prevent device damage from incorrect insertion, ensuring safe and worry-free use.

Notably, this expansion board is perfectly compatible with the color recognition system. The terminal colors on the expansion board, the terminals on the sensors, and the software programming blocks all correspond, creating an intuitive and unified color logic from hardware connection to software programming. This significantly reduces the operational difficulty for users, especially beginners, making the realization of creative ideas smoother and more efficient.

In terms of structural design, the spacing of the fixing holes on the expansion board precisely matches the building block spacing, allowing flexible integration with various building block structures. Whether you're building simple models or complex mechanical devices, the seamless compatibility fully expands your creative possibilities.
