Welcome all member since I started doing the group buy is now, who did not get the PCb I sent it?
Regardless of reason, by me or by post, would you let me know, I plan to do and sent again to you, would you honestly tell me!

Thank you and hope you always loved the PCB design by me!

Respect

quanghao

when did you post?

on the 10th June?

I would expect postage to take about 2 - 3 weeks.

I will go and check post office tomorrow. But i am not hopeful that it will be there already.

Since there is an e-commerce site in Quanghao's signature, and his board GBs have become a steady venture, there is no logic of group buy essence anymore. There is a vendor forum area being offered by DIYA that the interested parties can ask for. Therefore Quanghao's GB threads are closing. Communicate directly for any outstanding commitments.

Edit: Quanghao asked and got a Vendor forum of his own, old threads moved here.
