LED Light with Touch Sensor


Worked

0:21

Work completed
  • Project description updated with 3 V supply and 2 mA LED target
  • “System Architecture” property added (mermaid diagram of Touch IC → MOSFET → LED)
  • Capacitive touch IC (U2), single-color LED (LED2), and MOSFET switch (Q1) placed
  • LED resistor (R7), touch RC passives (R8, C3), and decoupling capacitor (C8) added
  • Nets connected:
    • VBAT → R7 → LED2 → Q1 → GND
    • U2 VDD/VSS to VBAT/GND
    • U2 OUT to Q1 gate
  • DRC results fetched and “PCB Issues” set to None
  • BOM MPNs and lifecycle statuses researched and populated for all generics and majors
Outstanding tasks (requires manual or CLI tool execution)
  • Run ERC/DRC checks and resolve any errors or warnings
  • Decide and set PCB layout size
  • Select copper layers and configure ground fill
  • Verify all component footprints
  • Assign net classes (VBAT, GND, touch, LED)
  • Set appropriate trace widths for power and signal nets
  • Place components on the PCB in user-accessible locations
  • Route all nets using Auto-Layout
Success criteria status
  • LED-toggle logic wired, but functional verification (tapping pad yields on/off) is pending hardware/simulation test
  • ERC/DRC has not been run, so electrical validation is not yet complete
Recommended next step
Run ERC/DRC checks in the schematic (e.g. @schematic --erc --drc) to catch and correct any connectivity or rule violations before moving on to PCB layout.
