Q: You have a microcontroller on each module, isn’t that a bit overkill?
A: Power-only modules don’t feature a microcontroller (MCU) but all other modules do. MCUs are critical for communication and reconfigurability. The small increase in cost and power consumption is dwarfed by huge gains in modularity, scalability and reusability. Having their own MCUs make Hexabitz modules function as standalone boards as well, reducing your overall system cost and size.
