PCB Design for RF Energy Harvesting BLE System
Thought
Work completed
- Updated project description with detailed goals and added hashtags (#RF, #EnergyHarvesting, #BLE).
- Defined system architecture and saved a mermaid diagram in project properties.
- Placed edge-mount SMA connector J1.
- Added AEM10941 PMU component U1.
Remaining tasks
- Add SMS7630-040LF rectifier and assign anode/cathode to RF_IN/RECT_DC nets.
- Integrate nRF52810 (Raytac MDBT42Q) BLE module with SWD pads and STATUS_LED.
- Place KR-5R5C334-R supercapacitor and set capacitance/voltage properties.
- Configure MPPT (R1, R2) and OVP/UVP (R3, R4) resistor dividers.
- Complete all decoupling networks on VIN_DC, VSTOR, VOUT.
- Create SWD and test-pad connectors for RF_IN, RECT_DC, VSTOR, VOUT, GND.
- Make all net connections per reference schematic.
- Perform schematic review and validate part ratings.
- Prepare PCB layout (stackup, zones, controlled-impedance trace, thermal via stitching).
- Define layout rules, place components, and route nets.
- Run ERC/DRC and generate outputs for production.
Success criteria status
- No nets or functional connections implemented yet; layout not started. All criteria remain unmet.
Next step
Proceed to the Connectivity phase: place the SMS7630-040LF rectifier, create the RF_IN and RECT_DC nets, and wire the SMA connector through the rectifier to the PMU VIN_DC input.
