People have asked us to create a wearable biometric data gathering device (see our philometer project) and this board would be really fun to build around.  Nicely done!

Very interesting project.

Have you any idea of how much this board will cost?

  Are you sure? yes | no

bobricius wrote 02/19/2017 at 09:50 point

about 100$ 20pcs ....20$ for 2mm, 20$ ENIG, 25$ steel stencil (soldering lot of led without reflow is suicide ) and rest is for boards. Boards shipped and awaiting soon delivery :)

  Are you sure? yes | no

What is this ridiculous site format?  Can't make head nor tail of it...

  Are you sure? yes | no

Ridiculous site is (and always has been) ridiculous.  Can't figure out if it's the summer intern or a big committee to blame.

  Are you sure? yes | no
