information about BOE RevB

kinougromit

Hi all,

I've just receive the BOE board. but I cannot get the relevant info dealing with the schematics of the board revB.

I'm always reaching the 32900revA from the regular web site or 32910revA from the support link on the web page.

and on the board itself it is written 32900revB

the ADC is a 10 pins on these schematics, and on the board I have it is a 16 pins, and the two LEDs close to the ADC are vertical, and the FTDI chipset is QFN as well...

thx,

Welcome to the forums!

I also have a Rev B board, and my ADC, (next to the reset switch), is 16 pins

Do you have a picture of the chip in question?

kinougromit

thx,


no, I do not have any picture of it. You're right the ADC is on the rigth side of the switch and left of reset btn.

it is written
79938
UZ-0
#212

for me it is a AD chipset but not sure at all ...

The Bill of Materials calls out AD7993BRUZ for the A/D. The inputs are accessed on the black header on the lower right side of the breadboard.

Data Sheet is here:

by the way do you have the full schematics ... in order to know to which pins of the propeller it is connected ... and also to check the other ones ...

thx,

it could be nice to publish the revB and avoid questionning.

Thx a lot "Publison".

I believe the only difference between the "A" and "B" revision, is the deletion of the Surface Mount pads on the back of the board, as indicated on page 6 of this document and access to the XBEE header and SD socket.:
