Legacy (Green) Cellular Notecards fail to Enable Cellular Modem when used in Notecarrier XS

Issue Description

If you are using Notecarrier XS with a Notecard Cellular (Legacy) device (a.k.a. a green Notecard), the shield over the modem can touch the VGPS_OUT pad, initiating a short.

This may cause the Notecard’s VMODEM regulator to heat up and not generate enough voltage to enable the modem.

Workaround

Cover the affected pins with a non-conductive tape such as Kapton tape.

Issue Mitigated with New Shipments and Manufacturing

This issue has been mitigated with conformal coating or Kapton tape. We
recommend not removing the Kapton tape if using Notecarrier XS with a green Notecard Cellular (Legacy).
