PCB

fellow lainons, sorry but i couldn't find a dedicated thread to post this in but, how could i find a cheaper option for this board? or even find some reverse engineered schematics? thanks in advance. https://shop.openbci.com/products/ganglion-board?variant=13461804483

>>7719 >or even find some reverse engineered schematics? I don't know man, that cog+lockway logo on the top right of the board is usually your signal to say "oh look, it wasn't designed by corporate asswipes", it's open-source open-hardware: https://github.com/OpenBCI/Ganglion_Hardware_Design_Files Are you trolling me? Oh well, this post is months old anyways.

>>8200 Not him, but getting access to the chips might be hard, and fabbing your own is also pretty difficult (not to mention more expensive than just buying the damn thing).

>>7719 I had a look at the schematic and BOM, it looks like there is about 100$ worth of parts and you are in about 20$ for the PCB. So definitively doable to DIY cheaper than retail. A few parts are generally out of stock so you will need alternatives but the biggest one, the MCU is available which is lucky as it is hard to source MCUs these days. Protip: use the BOM import tool on sites like LCSC to quickly find parts and prices. TLDR; doable with a bit of work, better yet doable in 2022

>>9001 Nice! Good work. That’s a much better price
