Hey Zhenyu, 

I'll send them out today. 

The connectors were a bit tricky to solder - the connectors were reused from 
the V2.1 T-Boards, and so had solder on the pins after removal. I couldn't 
use hot air to re-install them because the boards were double sided, so I did 
my best to solder them to the new t-b0ard prototypes. It's very possible it's 
a poor connection on the remaining two boards as well.

Hi Mike,

As I mentioned, out of the four cable/T-cables you sent to me, two of them 
exhibit a problem in readout, while the 3rd one has a connector detached. I 
think we should find out what problems the first two had, and make sure the 
production cable/T-boards won’t have the same problem. I am thinking to send 
them to you for examination. Before doing that, can you please send me maybe 
three more cable/T-board you have (assuming they are fully assembled)? 

Thanks,
Zhenyu
