To tailor a new wearable-health system with different sensors plus an onboard AI engine, let’s firm up your requirements. Could you answer:
  1. Sensor suite
    • Which vital signs or environmental parameters must it measure? (e.g., SpO₂, temperature, motion, glucose)
  2. AI functionality
    • What processing do you need on-board? (e.g., anomaly detection, signal filtering, ML inference)
    • Target throughput or model size?
  3. Form factor & power
    • Max size/weight and battery life goal?
    • Recharge method (USB, wireless)?
  4. Connectivity & UI
    • How will data be relayed? (BLE, Wi-Fi, cellular?)
    • Local user interface? (LEDs, display, haptics?)
  5. Regulatory & safety
    • Any specific medical or EMI standards to meet?
Once we have these, I can sketch a block-level architecture (power, sensor front-end, AI SoC, comms, display, battery management). Let me know!

To connect a charging controller to the battery in your wearable pregnancy monitoring system, you need to ensure that the flow of power is correctly managed. Based on the standard operation, the charging controller will manage charging the battery and providing power to the system when the external charger is connected.
Here are the key connections:
  1. Connect Charging Module to Battery:
    • Connect [charging−module]:BAT+[charging-module]:BAT+ to [battery]:positive[battery]:positive terminal.
    • Connect [charging−module]:BAT−[charging-module]:BAT- to [battery]:negative[battery]:negative terminal.
  2. Connect Charging Module to System Power:
    • Connect [charging−module]:OUT+[charging-module]:OUT+ to the power input of your system, typically [voltageregulator]:VI[voltage regulator]:VI if it requires regulated voltage.
    • Connect [charging−module]:OUT−[charging-module]:OUT- to the system ground, which may be connected to [voltageregulator]:GND[voltage regulator]:GND or [esp32−c3mini−1]:GND[esp32-c3 mini-1]:GND.
  3. Connect Input for Charging:
    • Connect [charging−module]:IN+[charging-module]:IN+ to the positive terminal of your charging supply.
    • Connect [charging−module]:IN−[charging-module]:IN- to the negative terminal of your charging supply.
Here's a concise format for the connections:
  • Connect [charging−module]:BAT+[charging-module]:BAT+ to [battery]:positive[battery]:positive terminal.
  • Connect [charging−module]:BAT−[charging-module]:BAT- to [battery]:negative[battery]:negative terminal.
  • Connect [charging−module]:OUT+[charging-module]:OUT+ to [voltageregulator]:VI[voltage regulator]:VI.
  • Connect [charging−module]:OUT−[charging-module]:OUT- to [voltageregulator]:GND[voltage regulator]:GND.
  • Connect [charging−module]:IN+[charging-module]:IN+ to the positive terminal of your charging supply.
  • Connect [charging−module]:IN−[charging-module]:IN- to the negative terminal of your charging supply.
Should I carry out these connections on your schematic? Also, please confirm if the [battery][battery] element needs to have explicit pins listed or if it's connected externally.
