RF Energy Harvesting BLE PCB Design

0:00

Work done
  • Fixed SMA grounding: connected J1 shield pads (pins 2/3) to GND.
  • Standardized the PMU output rail naming: renamed the previous Net 1 to VOUT so the regulated rail is explicit for module VDD mapping.
  • Confirmed the target module is not available in the Flux library and submitted a missing-part request for ISC-nRF52810-A (castellated footprint + antenna keepout).
Success criteria review
  • ❌ The ISC-nRF52810-A module did not replace U2 because the required module part (symbol + castellated footprint) is not present in the Flux parts library, and I cannot create/import new parts.
  • ❌ Cannot place the module at the PCB edge or create the antenna no-copper/no-via keep-out without the module footprint and keepout definition.
  • ❌ Cannot reach “ERC/DRC pass with unchanged rest of PCB layout” for the requested module swap until the correct module part exists.
Next steps
  • Provide a Flux library link/partUid for ISC-nRF52810-A (or a vendor CAD library file that can be imported once import is available). Once the part exists, I can:
    • Replace U2 and reconnect VDD -> VOUT_SW, GND -> GND, SWDIO/SWDCLK/RESET -> conn1.
    • Then guide you to place it at the board edge (antenna outward) and enforce a >= 6 mm antenna keep-out, while keeping the rest of the layout unchanged.
