Mars PM3 Product Change Notification
The revision 5.2 of the Mars PM3 base board is not equipped any longer with the I2C GPIO expander SX1505I087TRT. This part is end-of-life and no compatible replacement component is available. See Known Issues and Changes for more information.
Design changes might be necessary when migrating designs from earlier revisions. The Patch Specification provides more information on signals around the I2C GPIO expander and possible connectivity options. The configuration of these signals cannot be performed during runtime any longer.
