| The major questions here are: How much processing power do you require for the task, will a single-core processor suffice, or do you need a dual-core? Keep in mind that a multicore processor will be significantly faster but will consume a lot more energy. Therefore, you would want to consider if a multicore is necessary. | The major questions here are: How much processing power do you require for the task, will a single-core processor suffice, or do you need a dual-core?

| This might not be relevant in the case of the Hive Markerspace assuming all microcontrollers are loaned for free. However, whenever designing an embedded system, you always think about its affordability. Who is your target audience? Considering your cost of production, do you think this is an affordable product for your general audience? A microcontroller’s price can be a significant portion of your production cost. | This might not be relevant in the case of the Hive Markerspace assuming all microcontrollers are loaned for free.
