RIT will permanently shut down the RIT Wiki (Confluence wiki) on February 2, 2024. Review the Wiki Shut Down Overview for information on alternative tools, exporting content from the wiki, and other FAQs.
The team ordered some parts for this phase. This page is about the stance of the budget and the BOM at the end of phase 3. The first figure shows the budget spreadsheet which explains in detail the current parts that the team has ordered and the amount of the budget spent on those parts. There are two similar orders from both Digi-Key and Mouser as there was an issue with the Digi-Key order with the parts being out of stock and needing to wait for the supplies to refill. We decided that it would be good to order some of the parts from Mouser since they had the parts in stock and wouldn't delay the progression with testing the components. The team at the end of phase 3 has spent $189.91 to test and prototype the system. The parts ordered are the main micro-controller for our system, jumper wires, prototype boards so the MCU can give access to the pinouts, the solar panels we will be testing with, a solar lithium charger to charge the batteries from the solar panels, 3.3V voltage regulator, and 2 different batteries. The figures below show the bill of materials (BOM) along with the budget chart of the BOM. The price is different from the budget as it doesn't include the prices of the shipping price and the BOM only includes the parts that will be on the final prototype therefore there will be a mismatch with the budget spreadsheet. The BOM includes the main MCU, prototype board, jumper wires, solar panels, lithium-ion charger, 1200mAh battery, and 350mAh battery. The total of the BOM currently is $171.63 which is equivalent to 4.3% of the budget. As we progress through this project the BOM and budget will be updated accordingly. Bill of Material (BOM)
