The Elecrow page says that the analog front end used on the board is a ADS1299. The eight channel version of it is 60€+VAT on Digikey. The rest of the parts is most likely very cheap.
- ron_87 3y agoyes, but also ICs for Voltage! I use with the low noise. Also price for PCB board and for soldering and in my case also included software) But anyway I will try make price lower in the near future
- _Microft 3y agoThe BoM is of course only a small part of the cost and there is lots of work time and prototypes that need to be paid off by selling finished devices. I‘m sorry if that sounded like I thought that the price might be too high. Thanks for your efforts!
- ron_87 3y agoyou are very polite, thank you very much

- gorkish 3y agoI have tremendous respect for your efforts and goals. I should have reiterated that in my original comment. If you need to price these boards at $350 as a measure to ensure the success of your project, and you have people willing to participate at this stage of development at that price, more power to you. But your git repo looks like you need people to help and contribute, so I might suggest that it’s a little early to be amortizing your R&D costs onto the prototype hardware pricing. The projects I’ve seen successfully transit his stage usually arrange group buys and the like to get it into the hands of potential contributors as quickly and affordably as possible. This is also unlikely to be the last revision you want to make to the hardware.
