Q: Isn’t a 32-bit MCU an overkill for a smart LED module?

A: Yes! But all Hexabitz modules -whether it’s a complex Ethernet or IMU or a simple LED- share the same backend hardware and software. This what gives the platform its unmatched modularity and scalability. Cortex-M0 MCUs are small, cheap, power-efficient, yet capable of really wonderful things. Having an embedded MCU provides a cheaper and more compact alternative to connecting an LED breakout with an external controller.
