2 hours ago I got an email from Crowd Supply saying that my “Dabao Evaluation Board for Baochip-1x” order had shipped. Coincidence? Hmm…

wow it's transparent?

do UV and infrared photons not interfere with chip operations?

UV could have enough energy to change chemical bonds in the chip permanently?

They absolutely would, UV mostly since it’s higher energy. It’s not stated but it’s possible they’ve coated the chip with a UV opaque coating that is transparent to infrared though.
