PicoZed PUDC_B default

Former Member
Former Member over 9 years ago

There seems to be a discrepancy between the PicoZed 7015/7030 Schematic rev. C04 and the PicoZed 7015/7030 User's Guide v1.4 in relation to the default position of JT2.

Page 20 of the User's Guide states that JT2 is populated with a 1K resistor in the 1-2 position, pulling PUDC_B down by default.

A note on sheet 6 of the schematics says that the default is a 1K resistor in the 2-3 position, pulling PUDC_B high to VCCO_34.

Which is it?

    Hello William,

     

    The default postion of JT2 was changed from 1-2 (Ground) to 2-3 (VCCO-34) and documented in PCN15005:

     

    http://picozed.org/sites/default/files/documentations/Product%20Change%20Notification%20PCN15005.pdf

     

    So the JT2 position on your PicoZed will depend on if the board was build before or after PCN15005 went into effect.

     

    We missed updating page 20 in the Users Guide, thanks for letting us know.

     

    -Gary
