- The reasons why we decided Raspberry Pi B + against BEAGLEBONE Black are:
-
- - USB: B + Raspberry Pi has 4 X USB 2.0 CONNECTOR vs 1 X USB 2.0 CONNECTOR BLACK BONE beable. For our aquaponic system we need to connect with Arduino, camera and wireless Ethernet so we need more than one USB.
- - COMMUNITY: Raspberry Pi has sold over one million units and it have more coverage in the medial comunication and global exposure. Beagle Bone glack has a growing community but it's not enough. raspberry pi production generates 13 times more productivity than beaglebone black
- - As for our aquaponic system is as valid as Raspberry Pi B + bone Beagle but the price was decisive. As we can see from the chart the price of Raspberry Pi B + is € 31.95 compared to € 61.56 Beagle Bone Black. As our product has to have a lower price of 250 € we decided that was a good choice Raspeberry.
- To decide between a component or another, we have chosen a model of Arduino uno and other TI LaunchPad MSP430 . After we have made a comparison table
We have chosen Arduino Uno because:
-
- - Arduino have a massively huge community support. This is not to be under-estimated.
- - In Arduino there is no limit in a future expansion because the boards called 'shields' can be stacked on top of the board to add features, in the The MSP430 that’s not possible.
- - Arduino one Can run at 5V or 3.3V (or anywhere between 1.8V and 5V if you change oscillators) while The MSP430 caps out at 3.6V.
- - The Arduino have IO pins, 20 while the MSP430 have 16. It might not seem like a huge difference, but some projects where It's used 18 of those pins after using a pin expander to gain 8 more.
