where in the world are you located? I can order 1 and have it shipped to you. It can literally work with any BT controller. https://download.8bitdo.com/Manual/Receiver/md/MD_RR_ENG_Manual.pdf

I tried powering it through USB, it didn’t crash the system when you plug it in but crashes intermittently. It will be nice if it works, i will order the...

Anyway, I would love to send 1 to you if you want to work on it, at least to thank you for the hard work and wonderful design.

Ah, ok.. thanks for getting back.. I will test it again..

Actually, The Pentagon timing is the only 1 that works, the others won't even lock.

sadly, the clock is not 28Mhz exactly. it jitters at 27.78, 28.04, 28.09.

It think I my 74HCU04 might be the problem, the China seller might have give me 74HC04. Let me double check. Thanks.

is the clock out from 74HCU04N supposed to be a Square wave? mine is a sine wave. Ordering some 74HCU04 to try.

I have a RIGOL DS1052E. will it measure 28Mhz properly?
