The most significant changes to the BOM are in the output board and mainboard. The output board was revised numerous times and the parts in the final revision are significantly different than the previous BOM. If you have already purchased parts please see the change log for the parts that have been added. The mainboard design has not changed but some parts were changed from through-hole to surface mount. These parts now come pre-assembled and have been deleted from the BOM.
The Excel BOM and the online (cloud-based) BOM are the same. You can use either BOM, but the Excel BOM contains additional links for vendor carts and rare parts - and may be more useful. Please keep in mind that many of the parts are generic parts, including the resistors & capacitors. The parts numbers for these parts in the BOMs are the exact parts we used in our retail assemblies and parts kits, but there are many alternative parts that can be used as long as the part parameters are matched.
You may notice a new vendor Tayda Electronics has been added to the BOM. This is almost exclusively for 1/8W resistors. Both Mouser & Digikey have been changing vendors and/or changing availability of 1/8W resistors, and many part numbers from the previous BOMs have been updated due to lack of stock. 1/8W resistors can make for a cleaner assembly but are not required for any of the boards. 1/4W resistors can be substituted anywhere, but they will need to mounted in standing orientation.
Lastly, I want to give backers a better way to contact me. I am in contact with many of you directly via phone/text or email but it's difficult to manage. I receive hundreds of emails per day and want to find a better way to manage. If you would like to contact me directly please use
briancastro2@gmail.com and add [VS1 backer] in the subject line so I can filter your emails.
