Coloured iteadstudio PCBs

Good news everyone! iteadstudio is offering coloured PCBs at a lower cost.

After I had my very first set of PCBs manufactured, I was thinking of making my next set of PCBs in a different colour. However I found the price difference to be quite big and might just stick with plain old boring green instead.

Now that they’ve announced their new offering, I’d definitely go for a different colour for my next batch. They’ll be offering 8 boards instead of 10 (which is not a problem at all for me), and fixed thickness of 1.6mm and HASL finish – all for an extra US$5 more than their base PCB service. Their available colours are blue, white, yellow, red and black.
