Assembly ...

 

[piglet11]

Nice! Can't wait for results.
Do You have all necessary parts to finish?

Which Voltage are You use for logics? 1.8 or 3.3 V?

 

[acko]

3.3V *logic
Enough parts for initial batch only at this stage…

@acko … how is the testing going on ?

 

[acko]

Progressing but need to bring up slowly as it is new design, assembling and testing each section carefully before loading the main chips

 

[acko]

On board supplies and power sequencing tested good. Time to load the chips🙂

 

[Prodigy85]

Awesome Acko..

 

[acko]

Assembly and testing sections still going on… DAC core loaded

 

[acko]

Completed unit ready for tests ...
