Thx,i have been contract the d2wd &esp32 with the sales ,i also email the
sales@espressif.com but they said the espressif don't have
the hardware design for sample. So i am confused if the espressif can support the hardware of the esp32 d2wd for us?
samples state
this is allways a earliest time point, that the design is not produce but there are samples for engineering
this means too, that you allways must calculate ,that there comes design changes, edits and workaround on bugs or/and new revisions.
the reference design for samples is allways theoretically in this way and state. and i am sure, you will not get just in this sample state a handshake on reference design.
what there is, is engineering samples and there are just in time few groups working on the technical reference and details and so on.
MP state
mass production is the best time status you find a functionally base reference design, as soon as possible after there is also a design board with D2WD as SoC package soldered. and then you will find this in the espressif resource side,
example here. look to the
Design Guideline and
Hardware Resources
for some reason there is not allways all public posted or just in time in revise or new work or at the finnish state,
then it is allways the best way to contact your dealer/stocker / seller and ask for actually status on docu and reference designs.
i think you have few d2wd for testings and try to build a pcb on standard base D0WD
but be sensorec, the eMbeddedFlash is other handled as the SoC with the extern,
also there are some pins TBD also.
two question:
can i ask from where you come ( language) my base language is german if this helps more.
can i ask you further, on which base your protected pcb is founded, you must know there are pins not same functionally like d0wd
and so on, so your labor try i think is spontaneous and more on to try?
or have you basical information from your seller get or perhabs not the right info?
best wishes
