Updated Bill of Materials (BOM) #97

Open cornfeedhobo opened 5 months ago

cornfeedhobo commented 5 months ago

The current bill of materials is targeted at users that are already comfortable navigating suppliers. It would be nice if there was an updated BOM with concrete links to both DigiKey and Mouser.

I got all the material for this project from ali at a reasonable price. So for this project there is no need to buy from dedicated distributors.

Price/DeskHop 5.59 USD

Here the calculation: image

I know, that the price could be reduced with greater quantities, but I'm fine with price for that size of batch.

@cklimbac, Do you mind adding AliExpress links for each item on the list? I think that's what @cornfeedhobo is asking for.

I'll try to update it when I find a few mins, currently working on a major revision to include a single firmware image for both boards, web UI for configuration and firmware staging/sharing. Also managed to get DMA UART support so this should leave more cycles for USB and other stuff.

Wow, Digikey isn't far off, except for the quanities. I don't really want 1000 extra parts, so I might not choose AliExpress for that reason. Here's my list from Digikey.ca. https://www.digikey.ca/en/mylists/list/ZF5XS3NU7I

@maximumrozema this is tremendously helpful. It just offers more data points to compare and shop around while making sure you still get the part needed. Thank you!
