How can I help with this tracker right now? I can, for example:
  • Review the power path (USB-C to charger to battery to 3.3 V) and suggest improvements.
  • Size the TP4056 charge current and verify PROG/thermal limits.
  • Validate USB-C CC resistor values/wiring and ESD protection on D+/D−.
  • Check ESP32–A9G UART wiring and auto-boot/reset control.
  • Review SIM socket connections and ESD.
  • Sanity-check RF paths and antenna connectors.
