Changed the IO Expander to control the ground to RS41 rather than RESET via Q1. This totally fails and likely overloads the transistor. Unusable in this configuration unless powered directly from battery terminals.

Connecting to a via after scratching off soldermask. Accidentally exposed part of the ground plane and covered with kapton tape. Hot glue for stability.
